Description

There is at least one option accessed in MesosClusterScheduler that should come from the submission's configuration instead of the dispatcher's:

spark.mesos.fetcherCache.enable

Coincidentally, the spark.mesos.fetcherCache.enable option was previously misnamed, as referenced in the linked JIRA.
