Karthik Kambatla commented on YARN-1696:
----------------------------------------

bq. It's late, but after seeing the document, I think we should rename 
"yarn.resourcemanager.ha." configs to be "yarn.resourcemanager.failover."
I would prefer leaving it as ha. I understand your intention that this is 
primarily failover and not HA in the true sense of the word. I think these 
configs would apply to Active/Active and true HA, whenever we end up 
implementing that. Before naming the configs, I did spend sometime thinking 
about it. Also vaguely remember a conversation with Bikas about future true HA 
possibilities.
