> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 3.0.0, 0.23.9, 2.0.6-alpha
> Reporter: Robert Parker
> Assignee: Robert Parker
> Fix For: 3.0.0, 2.3.0, 0.23.10, 2.1.1-beta

> The issue is in RMNodeImpl where both RUNNING and UNHEALTHY states that
> transition to a deactive state (LOST, DECOMMISSIONED, REBOOTED) use the same
> DeactivateNodeTransition class. The DeactivateNodeTransition class naturally
> decrements the active node, however the in cases where the node has
> transition to UNHEALTHY the active count has already been decremented.
