      Description

      Submit a hive query which uses mapred to give the result(Say join query)
      If we submit a job to resourceManager process. it will create a MRAppMaster process to excute this task .
      MRAppMaster will create YarnChild process to excute Map task or reduce task.
      after task is finished,resourceManager will kill MRAppMaster and YarnChild process.
      When the hive client is about to get the progress from MRAppMaster ,the task is already finished ,so MRAppMaster process don't exist. so the client will try to connect it for ever.
      that's why hive client hangs.
