             Summary: closeAllForUGI causes failure in hiveserver2 when fetching large amount of data
                 Key: HIVE-4166
                 URL: https://issues.apache.org/jira/browse/HIVE-4166
             Project: Hive
          Issue Type: Bug
          Components: Security, Shims
    Affects Versions: 0.10.0, 0.11.0
            Reporter: Chris Drome
            Assignee: Chris Drome


HiveServer2 configured to use Kerberos authentication with doAs enabled throws an exception when fetching a large amount of data from a query.

The exception is caused because FileSystem.closeAllForUGI is always called at the end of TUGIAssumingProcessor.process. This affects requests on the ResultSet for data from a SELECT query when the amount of data exceeds a certain size. At that point any subsequent calls to fetch more data throw an exception because the underlying DFSClient has been closed.
