----------------------------------------
Summary: 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.
