Karthik Kambatla commented on YARN-1028:
----------------------------------------
Sorry for the digression. After discussion on HADOOP-10127, I think it is best
to not handle the delay in failover in this JIRA. Created YARN-1460 for a more
comprehensive overhaul of the connections from Client/ AM/ NM to the RM.
Will post a follow-up patch that captures any of the remaining work.
> 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.
