Rohith commented on YARN-2588:
------------------------------
In RMWebApp, we have code below where ApplicationACLManager and QueueACL
managers are part of ActiveServices instances binded to RMWebApp. IIUC, these
are not needed for starting in standby mode. I would like to know reason behind
why these 2 active service instances are binded to RMWebApp.?
{code}
if (rm != null) {
bind(ResourceManager.class).toInstance(rm);
bind(RMContext.class).toInstance(rm.getRMContext());
bind(ApplicationACLsManager.class).toInstance(
rm.getApplicationACLsManager());
bind(QueueACLsManager.class).toInstance(rm.getQueueACLsManager());
}
{code}
> Standby RM does not transitionToActive if previous transitionToActive is
> failed with ZK exception.

> Consider scenario where, StandBy RM is failed to transition to Active because
> of ZK exception(connectionLoss or SessionExpired). Then any further
> transition to Active for same RM does not move RM to Active state.
