---------------------------------

Hi Luke,

Looks like we may have missed uploading the patch here? Do you still have it around, by any
chance, if we still require this?

> Currently, if File sink is enabled for MRAppMaster or Resourcemanager, it does not populate
the file with all the available attributes. It would be useful for debugging and admin purpose
to have all the metrics populated in the file.
> For eg: MRAppMaster metrics currently logs value only for JobsRunning even though the
total available job level metrics are JobsCompleted, JobsFailed, JobsKilled, JobsPreparing
etc
