    Description

      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.
