> Key: HADOOP-7540
> URL: https://issues.apache.org/jira/browse/HADOOP-7540
> Project: Hadoop Common
> Issue Type: Improvement
> Components: metrics
> Affects Versions: 0.23.0
> Reporter: Ramya Sunil
> Assignee: Luke Lu
> Fix For: 0.23.0
>
>
> 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
