>                 Key: HADOOP-5848
>                 URL: https://issues.apache.org/jira/browse/HADOOP-5848
>             Project: Hadoop Common
>          Issue Type: New Feature
>          Components: metrics
>            Reporter: Edward Capriolo
>            Priority: Minor
>
> Create useful metrics for the TaskTracker Component. 
> * TasksStarted: Counter
> * TasksFailed: Counter
> If graphed, having these metrics will help administrators determine 
> graphically how task load is being spread. Also will help determine if 
> certain nodes have external conditions that are causing a task to fail.
