Vinod Kumar Vavilapalli commented on YARN-2859:
-----------------------------------------------

[~Naganarasimha] I agree that it (_MiniYARNCluster not letting you enable 
system-metrics-publisher inside RM_) is an existing issue even on 
trunk/branch-2 but the right solution is to fix the ordering in MiniYARNCluster 
to start things in the right order and propagate configuration correctly. I'll 
file a a separate ticket for this.

[~xgong], as you committed my first patch, can you review the addendum too? 
Thanks.
