Karthik Kambatla updated HADOOP-9945:
-------------------------------------
Attachment: hadoop-9945-2.patch
Offline, Alejandro suggested renaming the state to STOPPING instead of STOPPED
to capture that the HA service is not completely shutdown but about to.
Posting an updated patch.
> HAServiceState should have a state for stopped services

> HAServiceState, currently, has states for Initializing, Active, and Standby.
> For RM HA, it is useful to have another state "STOPPING". This is because
> YARN has a separate service model where Services are stopped and can't be
> restarted. When the Active/Standby RM is stopped, it can no longer go back to
> the Active/Standby state; setting the HAServiceState to Initializing is
> misleading.
