Vaibhav, As discussed offline, for 0.14, it would be good to have smaller patch
with just the change to call closeAllForUGI at the right place.
> HiveServer2 leaks FileSystem objects in FileSystem.CACHE

> Reporter: Vaibhav Gumashta

> Running over extended period (48+ hrs), we've noticed HiveServer2 leaking
> FileSystem objects in FileSystem.CACHE. Linked jiras were previous attempts
> to fix it, but the issue still seems to be there. A workaround is to disable
> the caching (by setting {{fs.hdfs.impl.disable.cache}} and
> {{fs.file.impl.disable.cache}} to {{true}}), but creating new FileSystem
> objects is expensive.
