Subject [jira] [Created] (YARN-2125) ProportionalCapacityPreemptionPolicy should only log CSV when debug enabled
Date Thu, 05 Jun 2014 07:59:01 GMT
Wangda Tan created YARN-2125:
--------------------------------

             Summary: ProportionalCapacityPreemptionPolicy should only log CSV when debug
enabled
                 Key: YARN-2125
                 URL: https://issues.apache.org/jira/browse/YARN-2125
             Project: Hadoop YARN
          Issue Type: Task
          Components: resourcemanager, scheduler
    Affects Versions: 3.0.0
            Reporter: Wangda Tan
            Assignee: Wangda Tan
            Priority: Minor
         Attachments: YARN-2125.patch

Currently, logToCSV() will be output using LOG.info() in ProportionalCapacityPreemptionPolicy.
Which will generate non-human-readable texts in resource manager's log every several seconds,
like

It's better to make it output when debug enabled.
