> Remove JobHistory.DEBUG_MODE for the following reasons:
> 1. No one seems to be using it - the config parameter corresponding to enabling it does
not even exist in mapred-default.xml
> 2. The logging being done in DEBUG_MODE needs to move to LOG.debug() and LOG.trace()
> 3. Buggy handling of helper methods in DEBUG_MODE; e.g. directoryTime() and timestampDirectoryComponent().
