Karthik Kambatla commented on YARN-2865:
----------------------------------------
Patch looks mostly good. Minor comments - we should reduce the visibility of
the class and its methods to package-private, mark it @Private @Unstable, and
add comments that this class is expected to be used only by RMContext and
ResourceManager. I just want to guard against new code using this instead of
RMContext; we might want this to be accessible in the future, but we should
probably keep the changes small in this JIRA.

> YARN-2588 handles exception thrown while transitioningToActive and reset
> activeServices. But it misses out clearing RMcontext apps/nodes details and
> ClusterMetrics and QueueMetrics. This causes application recovery to fail.
