Jian He commented on YARN-4559:
-------------------------------
new patch moved the curator#close in RM#serviceStop.
I cannot move the curator client creation into to LeaderElectorService because
LeaderElectorService will not be created if HA is not enabled.
I think the best way is just to merge the LeaderElectorService logic into
ZKRMStateStore itself. But that requires more refactoring on ZKRMStateStore
because ZKRMStateStore is not an alwaysOn service.
> Make leader elector and zk store share the same curator client
