> Currently, HiveProtoLoggingHook write event data to hdfs. The number of files can grow to very large numbers.
> Since the files are created under a folder with Date being a part of the path, hive should have a way to clean up data older than a certain configured time / date. This can be a job that can run with as little frequency as just once a day.
> This time should be set to 1 week default. There should also be a sane upper bound of # of files so that when a large cluster generates a lot of files during a spike, we don't force the cluster fall over.
