             Summary: Add a test to make sure NM will do application cleanup 
even if RM restarting happens before application completed
                 Key: YARN-2191
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.4.0
            Reporter: Wangda Tan
            Assignee: Wangda Tan

In YARN-1885, there's a test in 
TestApplicationCleanup#testAppCleanupWhenRestartedAfterAppFinished. But this is 
not enough, we need one more test to make sure NM will do app cleanup when 
restart happens before app finished. The sequence is,
1. Submit app1 to RM1
2. NM1 launches app1's AM (container-0), NM2 launches app1's task containers.
3. Restart RM1
4. Before RM1 finishes restarting, container-0 completed in NM1
5. RM1 finishes restarting, NM1 report container-0 completed, app1 will be 
6. RM1 should be able to notify NM1/NM2 to cleanup app1.
