Apache Kylin (v1.5.0) 发布，全新设计的新一代
逐层（By Level）算法 VS 逐块(By Split) 算法
一、工具准备
zookeeper3.4.6 （hadoop、hbase 管理工具） Hadoop.2.7.1 Hbase1.1.4 Kylin1.5.0-HBase1.1.3 Jdk1.7.80 Hive 2.0.0
二、虚拟主机
192.168.200.165 master1 192.168.200.166 master2 192.168.200.167 slave1 192.168.200.168 slave2
三、安装mysql
查看是否安装了mysql（master1）
[root@master1 ~]# ps -aux | grep mysql Mysql 3632 0.0 0.0 115348 1648?SsApr01 0:00 /bin/sh /wdcloud/app/mysql/bin/mysqld_safe mysql 4519 0.5 19.8 13895940 1591664 ? Sl Apr01 29:55 /wdcloud/app/mysql/bin/mysqld --basedir=/wdcloud/app/mysql --datadir=/wdcloud/data/mysql/data --plugin-dir=/wdcloud/app/mysql/lib/mysql/plugin --log-error=/wdcloud/data/mysql/data/mysql-error.log --open-files-limit=20000 --pid-file=/wdcloud/data/mysql/data/localhost.localdomain.pid --socket=/tmp/mysql.sock --port=3306
查看mysql版本
[root@master1 ~]# mysql --version mysql Ver 14.14 Distrib 5.6.29-76.2, for Linux (x86_64) using 6.2
登录mysql
[root@master1 ~]# mysql -uroot -p
Enter password:
四、安装jdk
查看安装版本
[root@master1 ~]# java -version java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
查看安装位置
[root@master1 ~]# which java /jdk1.7.0_80/bin/java
五、安装zookeeper
1.解压缩zookeeper到根目录下，进入目录，创建文件夹data、datalog、logs，配置环境变量
export ZOOKEEPER_HOME=/zookeeper-3.4.6 export PATH=$PATH:$ZOOKEEPER_HOME/bin
2.进入conf文件夹，复制zoo_sample.cfg 为zoo.cfg
3.修改zoo.cfg，增加红色内容，保存退出：
tickTime=2000 initLimit=10 syncLimit=5 dataDir=/zookeeper-3.4.6/data dataLogDir=/zookeeper-3.4.6/datalog clientPort=2181 server.0=master1:2888:3888 server.1=master2:2888:3888 server.2=slave1:2888:3888 server.3=slave2:2888:3888
修改conf下的log4j.properties文件，配置log文件生成位置
zookeeper.log.dir=/zookeeper-3.4.6/logs zookeeper.log.file=zookeeper.log zookeeper.tracelog.dir=/zookeeper-3.4.6/logs zookeeper.tracelog.file=zookeeper_trace.log
4.进入data文件夹创建文件“myid”，添加内容 0 保存退出
5.分发zookeeper文件夹到各个虚拟主机上的根目录上
scp –r /zookeeper-3.4.6 hadoop@master2:/ scp –r /zookeeper-3.4.6 hadoop@slave1:/ scp –r /zookeeper-3.4.6 hadoop@ slave2:/
6.修改每台主机上的myid ，按照顺序 master1 的myid 为0 master2 的myid 1 以此类推。
7.启动zookeeper
分别进入各个虚拟主机的zookeeper目录下启动zk服务
bin/zkServer.sh start
8.分别查询zookeeper的状态
bin/zkServer.sh status
[hadoop@master1 ~]$ zkServer.sh status JMX enabled by default Using config: /zookeeper-3.4.6/bin/../conf/zoo.cfg Mode: follower
Leader 是 zookeeper 主机启动了
Follower是zookeeper 从机启动了
9.停止zookeeper
Bin/zkServer stop
六、hadoop 高可用部署
1.解压缩hadoop2.7.1到hadoop家目录下，进入目录，创建文件夹tmp，hdfs/name，hdfs/data
2.进入~/hadoop/etc/hadoop，该文件夹包含了hadoop的大部分配置文件。
3.修改hadoop各配置文件如下：
core-site.xml

4.配置hadoop环境变量
export HADOOP_HOME=/home/hadoop/hadoop
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
5.查看hadoop是否安装配置成功
[hadoop@master1 ~]$ hadoop version Hadoop 2.7.1 Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r 15ecc87ccf4a0228f35af08fc56de536e6ce657a Compiled by jenkins on 2015-06-29T06:04Z Compiled with protoc 2.5.0 From source with checksum fc0a1a23fc1868e4d5ee7fa2b28a58a This command was run using /home/hadoop/hadoop/share/hadoop/common/hadoop-common-2.7.1.jar
6.分发hadoop文件夹到各个虚拟主机上的hadoop家目录上
scp -r ~/hadoop/ hadoop@master2:~ scp -r ~/hadoop/ hadoop@slave1:~ scp -r ~/hadoop/ hadoop@slave2:~
7.重新格式化hdfs系统
如果集群刚配置从没启动过，直接执行格式化操作。
如果集群已经格式化了后启动过，则先执行删除旧数据的操作后，在执行格式化操作。
1）删除旧数据
在 hdfs-ste.xml 配置了
dfs.name.dir = /home/hadoop/hdfs/name (namenode上存储hdfs名字空间元数据)
dfs.data.dir = /home/hadoop/hdfs/data (datanode上数据块的物理存储位置)
在core-site.xml中配置了
hadoop.tmp.dir = /home/hadoop/hadoop/tmp（namenode上本地的hadoop临时文件夹）
将各个集群节点这三个文件夹下面的文件和目录全部删除
2）执行格式化命令
hadoop namenode -format
3）格式化日志
DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it. 16/04/05 02:02:28 INFO namenode.NameNode: STARTUP_MSG: /*********************************************************** STARTUP_MSG: Starting NameNode STARTUP_MSG:

8.启停hadoop
#启动hadoop集群
注意事项：
1）各个集群节点之间能免密码登录彼此
2）确保各节点配置的myid和zoo.cfg里的一致，并先启动zookeeper集群
启动命令：sbin/start-all.sh 或者依次执行 start-dfs.sh 和 start-yarn.sh
[hadoop@master1 conf]$ start-all.sh Starting namenodes on [master1] master1: starting namenode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-namenode-master1.out slave2: starting datanode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-datanode-slave2.out master2: starting datanode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-datanode-master2.out master1: starting datanode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-datanode-master1.out slave1: starting datanode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-datanode-slave1.out Starting secondary namenodes [master2] master2: starting secondarynamenode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-secondarynamenode-master2.out starting yarn daemons starting resourcemanager, logging to /home/hadoop/hadoop/logs/yarn-hadoop-resourcemanager-master1.out slave2: starting nodemanager, logging to /home/hadoop/hadoop/logs/yarn-hadoop-nodemanager-slave2.out master2: starting nodemanager, logging to /home/hadoop/hadoop/logs/yarn-hadoop-nodemanager-master2.out master1: starting nodemanager, logging to /home/hadoop/hadoop/logs/yarn-hadoop-nodemanager-master1.out slave1: starting nodemanager, logging to /home/hadoop/hadoop/logs/yarn-hadoop-nodemanager-slave1.out
查看相关守护进程
NAMENODE（master1）
[hadoop@master1 logs]$ jps 12892 NameNode 13003 DataNode 13295 ResourceManager 13408 NodeManager 13826 QuorumPeerMain
SECONDARY NAMENODE（master2）
[hadoop@master2 ~]$ jps 10162 SecondaryNameNode 10052 DataNode 10245 NodeManager 4045 QuorumPeerMain
DATANODE（slave1/slave2）
[hadoop@slave1 ~]$ jps 13902 NodeManager 13789 DataNode 9331 QuorumPeerMain [hadoop@slave2 ~]$ jps 13697 QuorumPeerMain 18324 DataNode 18440 NodeManager
#停止hadoop集群
sbin /stop-all.sh
启动成功后可以访问web控制台查看集群信息：
NAMENODE：http://192.168.200.165:50070/
SECONDARY NAMENODE：http://192.168.200.166:9001
Nodes Of Cluster（YARN作业管理界面）: http://192.168.200.166:8088
9.启动jobhistoryserver
因为kylin中需要MapReduce任务调度，所以需要启动jobhistoryserver
[hadoop@master1 logs]$ mr-jobhistory-daemon.sh start historyserver
查看jobhistoryserver守护进程
[hadoop@master1 conf]$ jps 24419 JobHistoryServer
七、hbase 部署
1.解压缩hbase-1.1.4到hadoop家目录下，进入目录hbase
2.进入conf文件夹
3.修改hbase各配置文件如下：
hbase-env.sh
export JAVA_HOME=/jdk1.7.0_80
regionservers
master1
master2
slave1
slave2
hbase-site.xml（已优化）
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master1:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>master1,master2,slave1,slave2</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/zookeeper-3.4.6/data</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
<property>
<name>hbase.master.info.bindAddress</name>
<value>master1</value>

4.配置环境变量，优化内存
export HBASE_HOME=/home/hadoop/hbase export PATH=$PATH:$HBASE_HOME/bin export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -Xms1536m -Xmx2048m -Xmn1024m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70 -XX:PermSize=512m -XX:MaxPermSize=512m" export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -Xms1536m -Xmx2048m -Xmn1024m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70 -XX:PermSize=512m -XX:MaxPermSize=512m" export HBASE_THRIFT_OPTS="$HBASE_THRIFT_OPTS -Xms1024m -Xmx2048m"
5.分发hbase文件夹到各个虚拟主机上的hadoop家目录上
scp -r ~/hbase/ hadoop@master2:~ scp -r ~/hbase/ hadoop@slave1:~ scp -r ~/hbase/ hadoop@slave2:~
6.启停
bin/start-hbase.sh
bin/stop-hbase.sh
启动成功信息
[hadoop@master1 hadoop]$ start-hbase.sh master1: starting zookeeper, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-zookeeper-master1.out slave2: starting zookeeper, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-zookeeper-slave2.out master2: starting zookeeper, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-zookeeper-master2.out slave1: starting zookeeper, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-zookeeper-slave1.out starting master, logging to /home/hadoop/hbase/logs/hbase-hadoop-master-master1.out slave2: starting regionserver, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-regionserver-slave2.out master1: starting regionserver, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-regionserver-master1.out master2: starting regionserver, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-regionserver-master2.out slave1: starting regionserver, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-regionserver-slave1.out
查看相关守护进程
HMASTER（master1）
[hadoop@master1 hadoop]$ jps 14230 HMaster 14379 HRegionServer
HREGIONSERVER（master2、slave1、slave2）
[hadoop@ master2 ~]$ jps 10574 HRegionServer [hadoop@slave1 ~]$ jps 14230 HRegionServer [hadoop@slave2 ~]$ jps 18753 HRegionServer
出现的问题：集群节点的时间不同步
org.apache.hadoop.hbase.ClockOutOfSyncException
设置时间同步
#yum install ntpdate
# ntpdate 0.asia.pool.ntp.org
#rm -rf /etc/localtime
#ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
查看时间
date +%Y-%m-%d-%H:%M:%S
八、HIVE部署
仅在master1上部署即可
- 解压缩hive-2.0.0到hadoop家目录下，进入目录hive
- 进入conf文件夹
- 在mysql上创建元数据库hive
在master1上创建数据库hive(编码选latin，如果不选择latin，会出现问题)
#为hive数据库授权
grant all on hive.* to 'root'@'%' IDENTIFIED BY 'weidong' with grant option; flush privilege;
#设置mysql数据库为任意IP可连接
update user set host='%' where host='localhost';
4．修改hive各配置文件如下：
hive-site.xml
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://master1:3306/hive?createDatabaseIfNotExist=true</value>

<value>/home/hadoop/hive/logs</value>
</property>
<property>
<name>hive.aux.jars.path</name>
<value>file:///home/hadoop/hbase/lib</value>
</property>
<property>
<name>hive.metastore.uris</name>
<value>thrift://master1:9083</value>
<description>运行hive得主机地址及端口</description>
</property>
</configuration>
将日志配置打开
cp hive-log4j2.properties. template hive-log4j2.properties
cp hive-exec-log4j2.properties.template hive-exec-log4j2.properties
5．启动Hive
1）首先需要先启动元数据库
hive --service metastore &
启动成功信息
2016-04-06T11:46:10,157 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:main(5876)) - Starting hive metastore on port 9083 2016-04-06T11:46:10,210 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:newRawStore(499)) - 0: Opening raw store with implementation class:org.apache.hadoop.hive.metastore.ObjectStore 2016-04-06T11:46:10,299 INFO [main]: metastore.ObjectStore (ObjectStore.java:initialize(318)) - ObjectStore, initialize called 2016-04-06T11:46:12,284 INFO [main]: metastore.ObjectStore (ObjectStore.java:getPMF(402)) - Setting MetaStore object pin classes with hive.metastore.cache.pinobjtypes="Table,StorageDescriptor,SerDeInfo,Partition,Database,Type,FieldSchema,Order" 2016-04-06T11:46:15,345 INFO [main]: metastore.MetaStoreDirectSql (MetaStoreDirectSql.java:<init>(142)) - Using direct SQL, underlying DB is MYSQL 2016-04-06T11:46:15,352 INFO [main]: metastore.ObjectStore (ObjectStore.java:setConf(301)) - Initialized ObjectStore 2016-04-06T11:46:16,051 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:createDefaultRoles_core(586)) - Added admin role in metastore 2016-04-06T11:46:16,058 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:createDefaultRoles_core(595)) - Added public role in metastore 2016-04-06T11:46:16,239 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:addAdminUsers_core(635)) - No user is added in admin role, since config is empty 2016-04-06T11:46:16,715 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:startMetaStore(6020)) - Starting DB backed MetaStore Server with SetUGI enabled 2016-04-06T11:46:16,729 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:startMetaStore(6077)) - Started the new metaserver on port [9083]... 2016-04-06T11:46:16,729 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:startMetaStore(6079)) - Options.minWorkerThreads = 200 2016-04-06T11:46:16,729 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:startMetaStore(6081)) - Options.maxWorkerThreads = 1000 2016-04-06T11:46:16,730 INFO [main]: metastore.HiveMetaStore (HiveMetaStore.java:startMetaStore(6083)) - TCP keepalive = true
2）启动hive客户端
输入hive命令即可
[hadoop@master conf]$ hive SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/home/hadoop/hive/lib/hive-jdbc-2.1.0-SNAPSHOT-standalone.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/home/hadoop/hive/lib/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/home/hadoop/spark/lib/spark-assembly-1.4.0-hadoop2.6.0.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/home/hadoop/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

Logging initialized using configuration in file:/home/hadoop/hive/conf/hive-log4j2.properties Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases. hive>
检验hive客户端下能否查看/创建表
6．停止HIVE
ps –aux | grep hive 查看hive目前的进程PID，用kill杀掉即可。
7．常用命令
hive> show databases; OK default Time taken: 1.881 seconds, Fetched: 1 row(s) hive> use default; OK Time taken: 0.081 seconds hive> create table kylin_test(test_count int); OK Time taken: 2.9 seconds hive> show tables; OK kylin_test Time taken: 0.151 seconds, Fetched: 1 row(s) hive> select * from kylin_test; OK Time taken: 0.318 seconds
在hive数据库里查询
九、kylin部署
仅在master1上部署即可
1．了解kylin的两种二进制包
预打包的二进制安装包：apache-kylin-1.5.0-bin.tar.gz
特别二进制包：apache-kylin-1.5.0-HBase1.1.3-bin.tar.gz
说明：特别二进制包是一个在HBase 1.1+环境上编译的Kylin快照二进制包；安装它需要HBase 1.1.3或更高版本，否则之前版本中有一个已知的关于fuzzy
key过滤器的缺陷，会导致Kylin查询结果缺少记录:HBASE-14269。此外还需注意的是，这不是一个正式的发布版(每隔几周rebase KYLIN 1.3.x 分支上最新的改动)，没有经过完整的测试。
2．解压缩apache-kylin-1.5.0-HBase1.1.3-bin.tar.gz到hadoop家目录下，进入目录kylin
3．在/etc/profile里配置KYLIN环境变量和一个名为hive_dependency的变量
export KYLIN_HOME=/home/hadoop/kylin export PATH=$PATH:$ KYLIN_HOME/bin export hive_dependency=/home/hadoop/hive/conf:/home/hadoop/hive/lib/*:/home/hadoop/hive/hcatalog/share/hcatalog/hive-hcatalog-core-2.0.0.jar
这个配置需要在从节点master2,slave1,slave2上同时配置，因为kylin提交的任务交给mr后，hadoop集群将任务分发给从节点时，需要hive的依赖信息，如果不配置，则mr任务将报错为: hcatalogXXX找不到。
4.修改kylin的启动脚本kylin.sh
1）显式声明 KYLIN_HOME export KYLIN_HOME=/home/Hadoop/kylin 2）在HBASE_CLASSPATH_PREFIX中显示增加$hive_dependency依赖 export HBASE_CLASSPATH_PREFIX=${tomcat_root}/bin/bootstrap.jar:${tomcat_root}/bin/tomcat-juli.jar:${tomcat_root}/lib/*:$hive_dependency:$HBASE_CLASSPATH_PREFIX
5．检查环境是否设置成功
[hadoop@master1 conf]$ check-env.sh KYLIN_HOME is set to /home/hadoop/kylin
6．进入conf文件夹，修改kylin各配置文件如下：
kylin.properties
kylin.owner=wdcloud@kylin.apache.org kylin.rest.servers=master1:7070 kylin.hdfs.working.dir=/home/hadoop/kylin/kylin_hdfs_working_dir kylin.job.remote.cli.working.dir=/home/hadoop/kylin/kylin_job_working_dir #定义kylin用于MR jobs的job.jar包和hbase的协处理jar包，用于提升性能。 kylin.job.jar=/home/hadoop/kylin/lib/kylin-job-1.5.0-SNAPSHOT.jar kylin.coprocessor.local.jar=/home/hadoop/kylin/lib/kylin-coprocessor-1.5.0-SNAPSHOT.jar
将kylin_hive_conf.xml和kylin_job_conf.xml的副本数设置为4
<property>
<name>dfs.replication</name>
<value>4</value>
<description>Block replication</description>
</property>
7．启动和停止kylin
#确认必须启动的服务：
1)hadoop2的hdfs/yarn/jobhistory服务
start-dfs.sh
start-yarn.sh
mr-jobhistory-daemon.sh start historyserver
2)hive 元数据库：hive --service metastore &
3)zookeeper
4)hbase ：start-hbase.sh
#检查hive和hbase的依赖
[hadoop@master1 kylin]$ find-hive-dependency.sh
[hadoop@master1 kylin]$ find-hbase-dependency.sh
#启动和停止kylin的命令如下：
[hadoop@master1 kylin]$ kylin.sh start
[hadoop@master1 kylin]$ kylin.sh stop
Web访问地址
http://192.168.200.165:7070/kylin/login
默认的登录username/password 是 ADMIN/KYLIN.
十、kylin测试
1．测试Kylin自带的sample
Kylin提供一个自动化脚本来创建测试CUBE，这个脚本也会自动创建出相应的hive数据表。
运行sample例子的步骤：
① 运行${KYLIN_HOME}/bin/sample.sh脚本
[hadoop@master1 ~]$ sample.sh
关键提示信息：
KYLIN_HOME is set to /home/hadoop/kylin Going to create sample tables in hive... Sample hive tables are created successfully; Going to create sample cube... Sample cube is created successfully in project 'learn_kylin'; Restart Kylin server or reload the metadata from web UI to see the change.
#在MYSQL中查看此sample创建了哪几张表
# select DB_ID,OWNER,SD_ID,TBL_NAME from TBLS;
#在hive客户端查看创建的表和数据量（1w条）
hive> show tables; OK kylin_cal_dt kylin_category_groupings kylin_sales Time taken: 1.835 seconds, Fetched: 3 row(s) hive> select count(*) from kylin_sales; OK 10000 Time taken: 65.351 seconds, Fetched: 1 row(s)
② 重启kylin server 刷新缓存
[hadoop@master1 ~]$ kylin.sh stop
[hadoop@master1 ~]$ kylin.sh start
③ 使用默认的用户名密码ADMIN/KYLIN访问192.168.200.165:7070/kylin
进入控制台后选择project为learn_kylin的那个项目。
④ 选择测试cube “kylin_sales_cube”，点击“Action”-“Build”，选择一个2014-01-01以后的日期，这是为了选择全部的10000条测试记录。
选择一个生成日期
点击提交会出现重建任务成功提交的提示
⑤ 在监控台查看这个任务的执行进度，直到这个任务100%完成。
任务完成
切换到model控制台会发现cube的状态成为了ready，表示可以执行sql查询了
执行过程中，在hive里会生成临时表，待任务100%完成后，这张表会自动删除
kylin_intermediate_kylin_sales_cube_desc_20120201000000_20120201000000
执行过程中，在hbase里会生成永久的计算结果表，如：
KYLIN_PTQIXMC64A
如果build了两个以上的segment。还可以执行merge操作：
完成Merge任务
这时候HBASE里面不同的Segment表示的多张表也同时合并成了一张表，以节省磁盘空间
在Build过程中出现的问题：
当任务执行到第五步：创建HTable的时候，报错说创建的表不可用。
最终导致整个任务的失败 ERROR
|
2016-04-07 12:40:57,823 ERROR [pool-7-thread-5] steps.CubeHTableUtil:135 : Failed to create HTable java.lang.IllegalArgumentException: table KYLIN_9USQAHQQXC created, but is not available due to some reasons at com.google.common.base.Preconditions.checkArgument(Preconditions.java:92) at org.apache.kylin.storage.hbase.steps.CubeHTableUtil.createHTable(CubeHTableUtil.java:132) at org.apache.kylin.storage.hbase.steps.CreateHTableJob.run(CreateHTableJob.java:104) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84) at org.apache.kylin.engine.mr.common.HadoopShellExecutable.doWork(HadoopShellExecutable.java:60) at org.apache.kylin.job.execution.AbstractExecutable.execute(AbstractExecutable.java:114) at org.apache.kylin.job.execution.DefaultChainedExecutable.doWork(DefaultChainedExecutable.java:50) at org.apache.kylin.job.execution.AbstractExecutable.execute(AbstractExecutable.java:114) at org.apache.kylin.job.impl.threadpool.DefaultScheduler$JobRunner.run(DefaultScheduler.java:124) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) |
在社区提问：
http://apache-kylin.74782.x6.nabble.com/an-error-occurred-when-build-a-sample-cube-at-step-5-create-HTable-td4102.html
出错的原因：
因为在kylin中默认使用了snappy压缩算法导致的。
HDFS报错日志：

2016-04-12 12:05:05,726 ERROR [RS_OPEN_REGION-slave2:16020-0] handler.OpenRegionHandler: Failed open of region=KYLIN_VKRC32OKFP,,1460433926913.73fb906719a75b2733f046e87fbe8105., starting to roll back the global memstore size. org.apache.hadoop.hbase.DoNotRetryIOException: Compression algorithm 'snappy' previously failed test. at org.apache.hadoop.hbase.util.CompressionTest.testCompression (CompressionTest.java:91) at org.apache.hadoop.hbase.regionserver.HRegion.checkCompressionCodecs (HRegion.java:6300) at org.apache.hadoop.hbase.regionserver.HRegion.openHRegion(HRegion.java:6251) at org.apache.hadoop.hbase.regionserver.HRegion.openHRegion(HRegion.java:6218) at org.apache.hadoop.hbase.regionserver.HRegion.openHRegion(HRegion.java:6189) at org.apache.hadoop.hbase.regionserver.HRegion.openHRegion(HRegion.java:6145) at org.apache.hadoop.hbase.regionserver.HRegion.openHRegion(HRegion.java:6096) at org.apache.hadoop.hbase.regionserver.handler.OpenRegionHandler.openRegion (OpenRegionHandler.java:362) at org.apache.hadoop.hbase.regionserver.handler.OpenRegionHandler.process (OpenRegionHandler.java:129) at org.apache.hadoop.hbase.executor.EventHandler.run(EventHandler.java:129) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) 2016-04-12 12:05:05,727 INFO [RS_OPEN_REGION-slave2:16020-0] coordination.ZkOpenRegionCoordination: Opening of region {ENCODED => 73fb906719a75b2733f046e87fbe8105, NAME => 'KYLIN_VKRC32OKFP,,1460433926913.73fb906719a75b2733f046e87fbe8105.', STARTKEY => '', ENDKEY => 'x00x01'} failed, transitioning from OPENING to FAILED_OPEN in ZK, expecting version 1 2016-04-12 12:05:05,775 INFO [PriorityRpcServer.handler=18,queue=0,port=16020] regionserver.RSRpcServices: Open KYLIN_VKRC32OKFP,x00x01,1460433926913.06978b9fb1e423563a5aae7e1df044d8. |
解决方法：禁用压缩或者使用LZO作为压缩算法
官网给出的禁用压缩算法的方法如下：
To disable compressing MR jobs you need to modify
$KYLIN_HOME/conf/kylin_job_conf.xml by removing all configuration entries related to compression(Just grep the keyword “compress”). To disable compressing hbase tables you need to open $KYLIN_HOME/conf/kylin.properties and remove the line starting with kylin.hbase.default.compression.codec.
⑥ 切换到Insight 窗口执行SQL语句，例如：
|
select part_dt, sum(price) as total_selled, count(distinct seller_id) as sellers from kylin_sales group by part_dt order by part_dt; |
在Kylin中执行如上的sql统计只用了0.46s (十次取平均值)
在Hive里执行同一条sql统计语句，花费时间高达136秒
hive> select part_dt, sum(price) as total_selled, count(distinct seller_id) as sellers from kylin_sales group by part_dt order by part_dt;
Time taken: 136.489 seconds, Fetched: 731 row(s)
可见：kylin执行这条sql明显提升了效率。
其他测试语句：
① select * from kylin_sales;(1s内)
② 各个时间段内的销售额及购买量（0.39秒）
select part_dt, sum(price) as total_selled, count(distinct seller_id) as sellers
from kylin_sales
group by part_dt
order by part_dt;
③ 查询某一时间的销售额及购买量（0.40秒）
select part_dt, sum(price) as total_selled, count(distinct seller_id) as sellers from kylin_sales
where part_dt = '2014-01-01'
group by part_dt;
发现报错：
Error while compiling generated Java code:
public static class Record3_0 implements java.io.Serializable {
public java.math.BigDecimal f0;
public boolean f1;
public org.apache.kylin.common.hll.HyperLogLogPlusCounter f2;
public Record3_0(java.math.BigDecimal f0, boolean f1, ...
这是因为part_dt是date类型，在解析string到date的时候出问题，应将sql语句改为：
select part_dt, sum(price) as total_selled, count(distinct seller_id) as sellers
from kylin_sales
where part_dt between '2014-01-01' and '2014-01-01'
group by part_dt;
或者
select part_dt, sum(price) as total_selled, count(distinct seller_id) as sellers
from kylin_sales
where part_dt = date '2014-01-01'
group by part_dt;
④上面查询只用到了fact table，而没有用到lookup table。如果查询各个时间段所有二级商品类型的销售额，则需要fact table与lookup table做inner join（1.36s）
select fact.part_dt, lookup.CATEG_LVL2_NAME, count(distinct seller_id) as sellers
from kylin_sales fact
inner join KYLIN_CATEGORY_GROUPINGS lookup
on fact.LEAF_CATEG_ID = lookup.LEAF_CATEG_ID and fact.LSTG_SITE_ID = lookup.SITE_ID
group by fact.part_dt, lookup.CATEG_LVL2_NAME
order by fact.part_dt desc
