             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
