使用远程mysql作为元数据库安装Hive

环境：
CentOS6.6  hadoop1.2.1  mysql5.1.73

1、下载
[grid@hadoop1 ~]$ wget http://mirrors.cnnic.cn/apache/hive/hive-1.0.0/apache-hive-1.0.0-bin.tar.gz

2、解压
[grid@hadoop1 ~]$ tar -zxf apache-hive-1.0.0-bin.tar.gz

3、设置环境变量
[grid@hadoop1 ~]$ vim .bash_profile
HIVE_HOME=/home/grid/apache-hive-1.0.0-bin
PATH=$PATH:$HIVE_HOME/bin
CLASSPATH=$CLASSPATH:$HIVE_HOME/lib
export HIVE_HOME PATH CLASSPATH

[grid@hadoop1 ~]$ source .bash_profile

4、编辑Hive配置文件
a、编辑 hive-env.sh ，指定 HADOOP_HOME 、HIVE_CONF_DIR
[grid@hadoop1 conf]$ pwd
/home/grid/apache-hive-1.0.0-bin/conf
[grid@hadoop1 conf]$ cp hive-env.sh.template hive-env.sh
[grid@hadoop1 conf]$ vim hive-env.sh
# Set HADOOP_HOME to point to a specific hadoop install directory
HADOOP_HOME=/home/grid/hadoop-1.2.1
# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/home/grid/apache-hive-1.0.0-bin/conf

b、编辑 hive-site.xml ，修改数据库连接属性（javax.jdo.option.ConnectionURL/ConnectionDriverName/ConnectionUserName/ConnectionPassword）
[grid@hadoop1 conf]$ cp hive-default.xml.template hive-site.xml
[grid@hadoop1 conf]$ vi hive-site.xml
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://192.168.0.103:3306/hivedb</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>hive</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>123456</value>
    </property>
    <property>
        <name>hive.metastore.uris</name>
        <value>thrift://192.168.0.104:9083</value>
        <description>Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.</description>
    </property>
    <property>
        <name>hive.metastore.warehouse.dir</name>
        <value>/user/hive/warehouse</value>
        <description>location of default database for the warehouse</description>
    </property>

5、复制MySQL的JDBC驱动包到Hive的lib目录下

6、启动Hive（hadoop已启动）
启动服务端
[grid@hadoop1 ~]$ hive --service metastore
Starting Hive Metastore Server

启动客户端
[grid@hadoop1 ~]$ hive
