Alejandro Abdelnur commented on YARN-149:
-----------------------------------------
Karthik, high level seems OK to me. One thing I would add, for the HTTP
failover, if we have the RMHA wrapper approach the wrapper -when in standby-
would redirect HTTP calls to the active RM. While this does not cover the case
of rerouting if hitting an RM that crashed, it will cover the common case where
somebody hits the running standby.
