-----------------------------------

             Summary: logs in  MRAppMasterShutdownHook can not be output, beacuse Hook of Tasklog will be called to shutdown LogManager previously
                 Key: MAPREDUCE-6570
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6570
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster
    Affects Versions: 2.5.0
            Reporter: lachisis


priority of MRAppMasterShutdownHook  is 30, while priority of TaskLogHook is 50. 
when a applicationMaster received a signal to shutdown, actually TaskLogHook  will be called first. Then when MRAppMasterShutdownHook  be called next, no logs can be output.
