Varun Saxena commented on YARN-6147:
------------------------------------
This happens when NM is down but RM hasn't yet found out that it is down i.e.
NM expiry hasn't happened?
> Blacklisting nodes not happening for AM containers

> Black Listing of nodes are not happening in the following scenarios
> 1. RMAppattempt is in ALLOCATED and LAUNCH_FAILED event comes when NM is down.
> 2. RMAppattempt is in LAUNCHED and EXPIRE event comes when NM is down.
> In both these cases AppAttempt goes to *FINAL_SAVING* and eventually to
> *FINAL* state before *CONTAINER_FINISHED* event is triggered by
> {{RMContainerImpl}} and in the {{FINAL}} state {{CONTAINER_FINISHED}} event
> is ignored.
