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

             Summary: HadoopJobExecHelper Leaks RunningJobs
                 Key: HIVE-10781
                 URL: https://issues.apache.org/jira/browse/HIVE-10781
             Project: Hive
          Issue Type: Bug
          Components: Hive, HiveServer2
    Affects Versions: 1.2.0, 0.13.1
            Reporter: Nemon Lou


On one of our busy hadoop cluster, hiveServer2 holds more than 4000 org.apache.hadoop.mapred.JobClient$NetworkedJob instances,while only has less than 3 backgroud handler thread at the same time.
All these instances are hold in one LinkedList from org.apache.hadoop.hive.ql.exec.mr.HadoopJobExecHelper's  runningJobs property,which is static.
