Test failures don't look related and I cannot reproduce locally.

Upload patch 3 with exactly same content as patch 2, to trigger another QA run.

> 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.
