Delete empty timestamped directories
------------------------------------
Key: MAPREDUCE-4167
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4167
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobhistoryserver, mrv2
Affects Versions: 2.0.0, trunk
Reporter: Bhallamudi Venkata Siva Kamesh
Currently in the clean() method, we are deleting only the files/directories
inside *YYYY/MM/DD* directory and leaving those time stamped directories
(*YYYY/MM/DD*) as it is. As these are empty directories, I *think*, we should
delete these time stamped directories from FileSystem in the clean method.
