> 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.
