安装规划

服务名称	node01	node02	node03
impala-catalog	不安装	不安装	安装
impala-state-store	不安装	不安装	安装

修改配置(不是添加)

hives-site.xml

vim /export/servers/apache-hive-2.1.1-bin/conf/hive-site.xml

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
        <property>
                <name>javax.jdo.option.ConnectionURL</name>
                <value>jdbc:mysql://node03:3306/hive?createDatabaseIfNotExist=true</value>
        </property>
        <property>

</configuration>

将hive的安装包发送到node02与node01机器上

cd /export/servers/
scp -r apache-hive-2.1.1-bin/ node02:$PWD
scp -r apache-hive-2.1.1-bin/ node01:$PWD

启动相关服务

启动hive的metastore服务
node03机器启动hive的metastore服务

cd  /export/servers/apache-hive-2.1.1-bin
nohup bin/hive --service metastore &
nohup bin/hive -- service hiveserver2 &

注意：一定要保证mysql的服务正常启动，否则metastore的服务不能够启动
