Hive安装配置

http://www.cnblogs.com/linjiqin/archive/2013/03/04/2942402.html

Hbase In Action(HBase实战)和Hbase:The Definitive Guide(HBase权威指南)两本书中，有很多入门级的代码，可以选择自己感兴趣的check out。地址分别为 https://github.com/HBaseinaction https://github.com/larsgeorge/hbase-book 。

解压

$ tar -xzvf hive-x.y.z.tar.gz

tar zcvf hive-0.13.1.tar.gz hive

Hive配置

复制

cd conf

cp hive-default.xml.template hive-site.xml

cp hive-env.sh.template hive-env.sh

cp hive-log4j.properties.template hive-log4j.properties

cp hive-exec-log4j.properties.template hive-exec-log4j.properties

安装Mysql JDBC Connector

存储元数据是采用第三方的mysql数据库，这种情况下需要下载一个数据包mysql-connector-java-5.1.26-bin.jar，放到hive的lib目录下

cp mysql-connector-java-5.1.26-bin.jar hive/lib

修改配置

hive-site.xml

<?xml version="1.0"?>

hive.aux.jars.path的value中间不允许有空格，回车，换行什么的，全部写在一行上就行了，不然会出各种错。这些jar要复制到hive的lib中。

•hive-env.sh

# Set HADOOP_HOME to point to a specific hadoop install directory

HADOOP_HOME=/usr/local/hadoop

# Hive Configuration Directory can be controlled by:

export HIVE_CONF_DIR=/usr/local/hive/conf

启动hive

./hive -hiveconf hive.root.logger=DEBUG,console

报的各种错误及解决方法

报错：

缺少 htrace-core-2.04.jar

Specified key was too long; max key length is 767 bytes

这个问题，在网上看了一些资料，解决方法：

alter database hive character set latin1;

删除hive数据库，新建时设置为latin1即可；

设置数据库字符集

latin1 -- cp1252 West European

latin1_swedish_ci

启动

[root@iiot-test-server1 bin]# sh hive

Logging initialized using configuration in file:/usr/local/hive/conf/hive-log4j.properties

hive> show tables;

dev_opt

集成

只想使用hive查询hbase的数据，并不对hbase数据进行修改，因此使用外表即可。

Hbase中的表 dev_opt

'dev_opt', {NAME => 'opt', DATA_BLOCK_ENCODING => ' true

NONE', BLOOMFILTER => 'ROW', REPLICATION_SCOPE => '

0', COMPRESSION => 'NONE', VERSIONS => '1', TTL =>

'FOREVER', MIN_VERSIONS => '0', KEEP_DELETED_CELLS

=> 'false', BLOCKSIZE => '65536', IN_MEMORY => 'fal

se', BLOCKCACHE => 'true'}

dev_opt：只有一个列簇opt，下有两个列：opt:dvid,opt:value

创建外表

CREATE EXTERNAL TABLE dev_opt(key string, opt map<string,string>)

STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'

WITH SERDEPROPERTIES ("hbase.columns.mapping" = "opt:")

TBLPROPERTIES("hbase.table.name" = "dev_opt");

在hive中查询：

Hive> select * from dev_opt;

结果：

…

CREATE EXTERNAL TABLE dev_opt1(key string, dvid int, value string)

STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'

TBLPROPERTIES("hbase.table.name" = "dev_opt");

在hive中查询：
