Bilwa S T commented on YARN-8065:
---------------------------------
Black Listing of nodes are not happening in the following scenarios
# RMAppattempt is in ALLOCATED and LAUNCH_FAILED event comes when NM is down.
# RMAppattempt is in LAUNCHED nad 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.
> Application is failing when AM node is stopped
