Martin Loncaric updated SPARK-26192:
------------------------------------
Description:
There are at least two options accessed in MesosClusterScheduler that should
come from the submission's configuration instead of the dispatcher's:
spark.app.name
spark.mesos.fetchCache.enable
This means that all Mesos tasks for Spark drivers have uninformative names of
the form "Driver for (MainClass)" rather than the configured application name,
and Spark drivers never cache files unless the caching setting is specified on
dispatcher as well. Coincidentally, the spark.mesos.fetchCache.enable option
was misnamed, as referenced in the linked JIRA.
