CHD-5.3.6集群上hive安装

解压过后：

[hadoop@master CDH5.3.6]$ ls -rlt
total 8
drwxr-xr-x. 17 hadoop hadoop 4096 Jun  2 16:07 hadoop-2.5.0-cdh5.3.6
drwxr-xr-x. 11 hadoop hadoop 4096 Jun  2 16:28 hive-0.13.1-cdh5.3.6

1.配置hive-env.sh

export JAVA_HOME=/usr/local/jdk1.8
export HADOOP_HOME=/home/hadoop/CDH5.3.6/hadoop-2.5.0-cdh5.3.6
export HIVE_HOME=/home/hadoop/CDH5.3.6/hive-0.13.1-cdh5.3.6
export HIVE_CONF_DIR=/home/hadoop/CDH5.3.6/hive-0.13.1-cdh5.3.6/conf

2.配置hive-log4j.properties

hive.log.dir=/home/hadoop/CDH5.3.6/hive-0.13.1-cdh5.3.6/log

3.配置hive-site.xml

  这个寻找Apache-hadoop下的就可以，直接考过来就可以，在conf 目录下

4.配置环境变量

vi .bash_profile

export HADOOP_HOME=/home/hadoop/CDH5.3.6/hadoop-2.5.0-cdh5.3.6
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HIVE_HOME=/home/hadoop/CDH5.3.6/hive-0.13.1-cdh5.3.6
export HADOOP_INSTALL=$HADOOP_HOME
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:$MAVEN_HOME/bin:$HIVE_HOME/bin

5.拷贝MySQL包

cp /home/hadoop/hive/lib/mysql-connector-java-5.1.46.jar ./

6.hive命令报错：

Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient
解决方法：

格式化MySQL：
schematool -dbType mysql -initSchema

7.进入hive

hive (default)> 
              > CREATE TABLE dept(
              >   deptno int, 
              >   dname string, 
              >   loc string)
              > ROW FORMAT DELIMITED FIELDS TERMINATED BY ','  STORED AS textfile;
OK
Time taken: 0.57 seconds

8.准备数据：

vi detp.txt
10,ACCOUNTING,NEW YORK
20,RESEARCH,DALLAS
30,SALES,CHICAGO
40,OPERATIONS,BOSTON

9.装数据：

load data local inpath '/home/hadoop/tmp/detp.txt' overwrite into table dept;

10.查询：

hive (default)> select count(1) from dept;
Total jobs = 1
Launching Job 1 out of 1

In order to change the average load for a reducer (in bytes):
  set hive.exec.reducers.bytes.per.reducer=<number>

  set mapreduce.job.reduces=<number>
