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

             Summary: Clean up UGI objects in FileSystem cache for transactions
                 Key: HIVE-13151
                 URL: https://issues.apache.org/jira/browse/HIVE-13151
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.0.0
            Reporter: Wei Zheng
            Assignee: Wei Zheng


One issue with FileSystem.CACHE is that it does not clean itself. The key in that cache includes UGI object. When new UGI objects are created and used with the FileSystem api, new entries get added to the cache.

We need to manually clean up those UGI objects once they are no longer in use.
