> 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.
