It is now an epic and there are subtickets that can as far as I estimate be implemented within a sprint or less each, given the available prior work from the first attempt at MESOS-336.

> The slave should be smarter about how it handles pulling down executors.  In our environment, executors rarely change but the slave will always pull it down from regardless HDFS.  This puts undue stress on our HDFS clusters, and is not resilient to reduced HDFS availability.
