Robert Kanter updated YARN-5566: -------------------------------- Attachment: YARN-5566.001.patch When digging into this, I figured that the DECOMMISSIONG node must have thought it was still running apps, and so I added a bunch of extra print statements and saw that this was the case. While all RUNNING nodes had the correct counts, the DECOMMISSIONING node's count went back up somehow. I was looking at the state transitions, and saw that this one {code:java} .addTransition(NodeState.DECOMMISSIONING, EnumSet.of(NodeState.DECOMMISSIONING, NodeState.DECOMMISSIONED), RMNodeEventType.STATUS_UPDATE, new StatusUpdateWhenHealthyTransition()) {code} looked different from this analogue one {code:java} .addTransition(NodeState.RUNNING, EnumSet.of(NodeState.RUNNING, NodeState.UNHEALTHY), RMNodeEventType.STATUS_UPDATE, new StatusUpdateWhenHealthyTransition()) {code} despite calling the same transition. So I tried adding the UNHEALTHY state, and that fixed the problem.
