stefanlee created MAPREDUCE-7129:
------------------------------------

             Summary: Cannot assign container Container: maps.isEmpty=true
                 Key: MAPREDUCE-7129
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7129
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am
    Affects Versions: 2.4.0
         Environment: we have many mapreduce applications without reduce task, and we found a lot of  *Cannot assign container Container: maps.isEmpty=true* information in MRAppMaster log, they are unused containers  in *scheduledRequests.assign* and released by RM,  and MRAppMaster will hang 2 mimute at *getResource* ,i doubt if it's inconsistent between *ask* and *maps*?
            Reporter: stefanlee
