Subject [jira] [Created] (YARN-256) Increase retention of applications in AppManager without sending more applications to the UI
Date Mon, 03 Dec 2012 21:17:58 GMT
Derek Dagit created YARN-256:
--------------------------------

             Summary: Increase retention of applications in AppManager without sending more
applications to the UI
                 Key: YARN-256
                 URL: https://issues.apache.org/jira/browse/YARN-256
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 0.23.5
            Reporter: Derek Dagit


In very busy clusters we would like to retain applications longer so that users' links will
not expire too soon.  Very often links to application history expire before they can be followed.

Simply increasing max-completed applications has an adverse performance impact on the applications
list in the web UI because it presents the entire list of applications with a request.

Therefore, we would like some way to be able to increase the retention of applications without
increasing the number of applications sent to the Web UI.
