Eli Collins commented on HADOOP-7924:
-------------------------------------

bq. maybe we should rename FailoverController to ManualFailoverController? or 
even just ManualFailover? IMO "FailoverController" has always had a connotation 
of being some kind of daemon.

This could be used for automatic failover as well though right? I was thinking 
this class would eventually get a main method and become a daemon (the static 
methods would still support manual failover). If not, maybe rename HAFailover?

Updated patch coming that addresses your other feedback.
