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

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
