> 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.
