Navis commented on HIVE-11768:
------------------------------
[~thejas] I've left "FileSystem.deleteOnExit" problem for another issue because
"FileSystem.close" will not be called ever. Could it be removed from code
safely? I'm not sure on that.
> java.io.DeleteOnExitHook leaks memory on long running Hive Server2 Instances
