Masatake Iwasaki updated YARN-3705:

Attachment: YARN-3705.006.patch
bq. If we call resetLeaderElection inside the rmadmin.transitionToStandby(), it
will cause a infinite loop.
You are right. I need to make sure that resetLeaderElection is not called when
EmbeddedElectorService#becomeStandby calls transitionToStandy. Thanks for the
good catch, [~xgong].
I attached 006. Though I checked that the loop is not caused by starting RM-HA
manually with patched jar, it is difficult to test that in unit test.
> 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.
