Bikas Saha commented on YARN-1028:
----------------------------------
How do we know that the standby RM will be ready in that much time (if the
current RM has crashed)? What kind of network errors cause
failoverOnNetworkException to be triggered? Can they be caused due to glitches
in the network, thus we would fail over to the standby and failback again?
> Add FailoverProxyProvider like capability to RMProxy

> RMProxy layer currently abstracts RM discovery and implements it by looking
> up service information from configuration. Motivated by HDFS and using
> existing classes from Common, we can add failover proxy providers that may
> provide RM discovery in extensible ways.
