> Key: YARN-1101
> URL: https://issues.apache.org/jira/browse/YARN-1101
> 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
> Attachments: YARN-1101_b0.23_v1.patch, YARN-1101_v1.patch
>
>
> 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.
