             Summary: [MESOS] Improve data locality when launching new executors when dynamic allocation is enabled
                 Key: SPARK-16944
                 URL: https://issues.apache.org/jira/browse/SPARK-16944
             Project: Spark
          Issue Type: New Feature
          Components: Mesos
    Affects Versions: 2.0.0
            Reporter: Sun Rui


Currently Spark on Yarn supports better data locality by considering the preferred locations of the pending tasks when dynamic allocation is enabled. Refer to https://issues.apache.org/jira/browse/SPARK-4352. It would be better that Mesos can also support this feature.

I guess that some logic existing in Yarn could be reused by Mesos.
