Xuan Gong commented on YARN-3705:
---------------------------------
[~iwasakims] Thanks for working on this.
Here is one issue for this patch.
If we call resetLeaderElection inside the rmadmin.transitionToStandby(), it
will cause a infinite loop.
Basically, resetLeaderElection--> terminate and recreate zk client --> rejoin
the leader elector --> transitionToStandby -->resetLeaderElection
Could you check this, please ?
> forcemanual transitionToStandby in RM-HA automatic-failover mode should
> change elector state

> Executing {{rmadmin -transitionToStandby --forcemanual}} in
> automatic-failover.enabled mode makes ResouceManager standby while keeping
> the state of ActiveStandbyElector. It should make elector to quit and rejoin
> in order to enable other candidates to promote, otherwise forcemanual
> transition should not be allowed in automatic-failover mode in order to avoid
> confusion.
