Subject [jira] [Created] (SPARK-9817) Improve the container placement strategy by considering the localities of pending container requests
Date Tue, 11 Aug 2015 09:06:45 GMT
Saisai Shao created SPARK-9817:
----------------------------------

             Summary: Improve the container placement strategy by considering the localities
of pending container requests
                 Key: SPARK-9817
                 URL: https://issues.apache.org/jira/browse/SPARK-9817
             Project: Spark
          Issue Type: Improvement
          Components: YARN
            Reporter: Saisai Shao
            Priority: Minor


Current implementation does not consider the localities of pending container requests, since
required locality preferences of tasks will be shifted time to time. It is better to discard
outdated container request and recalculate with container placement strategy.
