Subject [jira] [Created] (YARN-4526) Make SystemClock singleton so AppSchedulingInfo could use it
Date Wed, 30 Dec 2015 00:31:49 GMT
Karthik Kambatla created YARN-4526:
--------------------------------------

             Summary: Make SystemClock singleton so AppSchedulingInfo could use it
                 Key: YARN-4526
                 URL: https://issues.apache.org/jira/browse/YARN-4526
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: scheduler
    Affects Versions: 2.8.0
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


To track the time a request is received, we need to get current system time. For better testability
of this, we are likely better off using a Clock instance that uses SystemClock by default.
Instead of creating umpteen instances of SystemClock, we should just reuse the same instance.
