1>.解压

    tar -zxvf apache-hive-1.2.1-bin.tar.gz

2>.设置环境变量

export HIVE_HOME=/home/hadoop/apache-hive-1.0.0-bin

export PATH=$PATH:$HIVE_HOME/bin

3>.修改配置文件

进入conf目录，首先将hive-env.sh.template和hive-default.xml.template进行复制并改名为hive-env.sh和hive-site.xml

hive-env.sh修改

export HADOOP_HEAPSIZE=1024

# Set HADOOP_HOME to point to a specific hadoop install directory

HADOOP_HOME=/home/hadoop/hadoop-2.4.1

# Hive Configuration Directory can be controlled by:

export HIVE_CONF_DIR=/home/hadoop/apache-hive-1.0.0-bin/conf

# Folder containing extra ibraries required for hive compilation/execution can be controlled by:

export HIVE_AUX_JARS_PATH=/home/hadoop/apache-hive-1.0.0-bin/lib

hive-site.xml修改

<configuration>

4>.拷贝mysql-connector-java-5.0.8-bin.jar到hive的lib下面

5>.在mysql中创建hive数据库 
create database hive;

6>.把jline-2.12.jar拷贝到hadoop相应的目录下，替代jline-0.9.94.jar，否则启动会报错

cp hive/lib/jline-2.12.jar  hadoop-2.6.0/share/hadoop/yarn/lib/

8>.在集群HDFS上创建和hive目录  hdfs dfs -mkdir /user/hive

7>.启动：bin/hive
