[jira] [Created] (YARN-1166) YARN 'appsFailed' metric should be of type 'counter'

Srimanth Gunturi created YARN-1166:
--------------------------------------

             Summary: YARN 'appsFailed' metric should be of type 'counter'
                 Key: YARN-1166
                 URL: https://issues.apache.org/jira/browse/YARN-1166
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.1.0-beta
            Reporter: Srimanth Gunturi


Currently in YARN's queue metrics, the cumulative metric 'appsFailed' is of type 'guage' - which means the exact value will be reported. 

All other cumulative queue metrics (AppsSubmitted, AppsCompleted, AppsKilled) are all of type 'counter' - meaning Ganglia will use slope to provide deltas between time-points.

To be consistent, AppsFailed metric should also be of type 'counter'.
