Target Version/s: 0.7.0
> Hive fails to work with OM HA

> Key: HDDS-3323
> URL: https://issues.apache.org/jira/browse/HDDS-3323
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Reporter: Namit Maheshwari
> Assignee: Hanisha Koneru
> Priority: Critical

> Hive fails to work with OM HA due to the below configuration issue:
> Please look at the below Hive client conf:
> {code:java}
> <property>
> <name>ozone.om.address.ozone1.om1</name>
> <value>xxx-7.xxx.root.zzz.site:9862</value>
> </property>
> <property>
> <name>ozone.om.address.ozone1.om2</name>
> <value>xxx-8.xxx.root.zzz.site:9862</value>
> </property>
> <property>
> <name>ozone.om.address.ozone1.om3</name>
> <value>xxx-6.xxx.root.zzz.site:9862</value>
> </property>
> {code}
>
> OM Server has below conf:
> {code:java}
> <property>
> <name>ozone.om.address.ozone1.om1</name>
> <value>xxx-6.xxx.root.zzz.site:9862</value>
> </property>
> <property>
> <name>ozone.om.address.ozone1.om2</name>
> <value>xxx-7.xxx.root.zzz.site:9862</value>
> </property>
> <property>
> <name>ozone.om.address.ozone1.om3</name>
> <value>xxx-8.xxx.root.zzz.site:9862</value>
> </property>
> {code}
> Let's say om3 is leader which is host xxx-8.xxx.root.zzz.site:9862 as per the
> OM server.
> Now let's say, client is talking to om1, and the server responds the
> suggested leader as om3, then client fails over to om3 which is host
> xxx-6.xxx.root.zzz.site:9862 according to it's conf, but according to the
> server it is xxx-8.xxx.root.zzz.site:9862.
> So, now the client will keep on talking to follower OM which is
> xxx-6.xxx.root.zzz.site:9862, and exhaust its retry count and finally the
> request will fail.
> Thus Hive fails to work with OM HA. We need to address it.
