hive配置远程metastore的方法：
1）首先配置hive使用本地mysql存储metastore（服务器A 111.121.21.23）（也可以使用远程mysql存储）
2）配置完成后，在服务器A启动服务：bin/hive --service metastore （默认监听端口是：9083）
3）配置hive客户端，修改hive-site.xml：（服务器B-需要有hadoop环境）
<property>
<name>hive.metastore.local</name>
<value>false</value>
<description>controls whether to connect to remove metastore server or open a new metastore server in Hive Client JVM</description>
</property>
<property>
<name>hive.metastore.uris</name>
<value>thrift://111.121.21.23:9083</value>
<description></description>
</property>
4）运行：bin/hive ,执行测试hql
5）hive客户端连接成功后，hive服务器端输出以下日志：
