MetaStore HA





前置条件

Hadoop、Zookeeper、Hive是可用的前提

Hive Server MetaStore启动

跟单节点配置一样，只不过在多台服务器上启动MetaSotre

启动：nohup $HIVE_HOME/bin/hive –metastore &

配置Hive Client HA

vi $HIVE_HOME/conf/hive-site.xml

添加配置如下:

<property>
<name>hive.metastore.uris</name>
<value>thrift://dw1:9083,thrift://dw2:9083</value>
<description>A comma separated list of metastore uris on which metastore service is running</description>
</property>
<property>
<name>hive.cluster.delegation.token.store.class</name>
