Bernd Mathiske commented on MESOS-336:
--------------------------------------

Getting close to finishing. Have tests running for caching, no caching, GC, extraction, no
extraction. Currently working on a test for slave recovery. After that, I will rebase and
post another patch, which will then be review-ready.

> 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.
