Review request for hive and Gopal V.


Bugs: HIVE-20259
    https://issues.apache.org/jira/browse/HIVE-20259


Repository: hive-git


Description
-------

Attached patch with utility DirectoryMarkerUpdate/Cleanup classes to create .cacheupdate files in the cache directory, to indicate that this directory should not be cleaned up by any other process performing DirectoryMarkerCleanup. This uses the last modify date of the .cacheupdate file to determine whether the file should be cleaned up, if the instance running cleanup determines this date is too old then the directory will be deleted.
