> 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.
