             Summary: Blacklisting nodes not happening for AM containers
                 Key: YARN-6147
                 URL: https://issues.apache.org/jira/browse/YARN-6147
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: Naganarasimha G R
            Assignee: Naganarasimha G R


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.
