> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Reporter: Rohith
> Assignee: Rohith

> 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.
