Sushanth Sowmyan commented on HIVE-13151:
-----------------------------------------

[~sershe]/[~wzheng] : I think this should be tracked for 2.0.1 as well as it's a pretty common
leak. Thoughts?

> 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.
