Subject [jira] [Created] (YARN-3857) Memory leak in ResourceManager with SIMPLE mode
Date Fri, 26 Jun 2015 10:14:04 GMT
mujunchao created YARN-3857:

             Summary: Memory leak in ResourceManager with SIMPLE mode
                 Key: YARN-3857
                 URL: https://issues.apache.org/jira/browse/YARN-3857
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.7.0
            Reporter: mujunchao
            Priority: Critical

 We register the ClientTokenMasterKey to avoid client may hold an invalid ClientToken after
RM restarts. In SIMPLE mode, we register Pair<ApplicationAttemptId, null> ,  But we
never remove it from HashMap, as unregister only runing while in Security mode, so memory
leak coming.
