Vinod Kumar Vavilapalli commented on YARN-1028:
-----------------------------------------------
Also, instead of a config YARN_MINICLUSTER_USE_RPC, why not indicate as part of
constructor? I wish the other configs were also set like that.
TestRMFailover
- verifyNodeManagerConnected() should perhaps move to MiniYARNCluster.
- verifyClientConnection() is similar utility but for the client-service? Then
we could move that too, and do it just by a getAppList or something instead of
creating new apps.
> 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.
