Srimanth Gunturi created YARN-989:
-------------------------------------

             Summary: MR2 specific metrics should be collected
                 Key: YARN-989
                 URL: https://issues.apache.org/jira/browse/YARN-989
             Project: Hadoop YARN
          Issue Type: Bug
          Components: api, applications
    Affects Versions: 2.1.0-beta
            Reporter: Srimanth Gunturi


We have a usecase to show the below information. We can find job count by calling the /apps
endpoint and filtering by type/state. But we need a way (JMX/API) to get the number of map/red
tasks that are running/waiting.

{noformat}
Total Jobs: x jobs
Tasks: Maps	a running / b waiting
Tasks: Reduces	c running / d waiting
{noformat}
