[jira] [Created] (HADOOP-11402) Negative user-to-group cache entries are never cleared for never-again-accessed users

Colin Patrick McCabe created HADOOP-11402:
---------------------------------------------

             Summary: Negative user-to-group cache entries are never cleared for never-again-accessed users
                 Key: HADOOP-11402
                 URL: https://issues.apache.org/jira/browse/HADOOP-11402
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Colin Patrick McCabe


Negative user-to-group cache entries are never cleared for never-again-accessed users.  We should have a background thread that runs very infrequently and removes these expired entries.
