-----------------------------------

As far as i can see ,the race condition mentioned here still exists, even
after using FileSystem#newInstance. That is because FileSystems are closed by
calling FileSystem.closeAllForUGI(ugi) int the cleanupBulkLoad function, and
FileSystems created by FileSystem#newInstance do share the same user, so they
will be closed by the FileSystem.closeAllForUGI(ugi) call.
Solution to this race condition might be more complicated ,e.g. reference
counting
> FileSystem not closed in secure bulkLoad
