> HDFS-14130 made ZKFC aware of the Observer Namenode and hence allows ZKFC
> running along with the observer NOde.
> The Observer namenode isn't suppose to be part of ZKFC election process.
> But if the Namenode was part of election, before turning into Observer by
> transitionToObserver Command. The ZKFC still sends instruction to the
> Namenode as a result of previous participation and sometimes tend to change
> the state of Observer to Standby.
> This is also the reason for failure in TestDFSZKFailoverController.
> TestDFSZKFailoverController has been consistently failing with a time out
> waiting in testManualFailoverWithDFSHAAdmin(). In particular
> {{waitForHAState(1, HAServiceState.OBSERVER);}}.
