Andrew Onischuk resolved AMBARI-12232.
--------------------------------------
Resolution: Fixed
Committed to trunk and branch-2.1
> upgradeHelper for a 2.1 -> 2.2 upgrade leaves Resource Manager unusable
> -----------------------------------------------------------------------
>
> Key: AMBARI-12232
> URL: https://issues.apache.org/jira/browse/AMBARI-12232
> Project: Ambari
> Issue Type: Bug
> Reporter: Andrew Onischuk
> Assignee: Andrew Onischuk
> Fix For: 2.1.0
>
>
> PROBLEM: The upgradeHelper script when upgrading from 2.1 -> 2.2 sets up YARN
> to use ZKRMStateStore. It also sets the zk-address to localhost:2181:
>
>
>
> "yarn.resourcemanager.store.class":
> "org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStore",
> "yarn.resourcemanager.zk-address": "localhost:2181",
>
> This leaves the RM unable to start because it has no quorum to connect to. The
> upgradeHelper should either not set the ZKRMStateStore, or it should be trying
> harder to populate a valid ZK quorum.
