-------------------------------------
Summary: Allow enabling Mesos fetch cache in coarse executor
backend
Key: SPARK-15994
URL: https://issues.apache.org/jira/browse/SPARK-15994
Project: Spark
Issue Type: Improvement
Components: Mesos
Affects Versions: 2.0.0
Reporter: Charles Allen
Mesos 0.23.0 introduces a Fetch Cache feature
http://mesos.apache.org/documentation/latest/fetcher/ which allows caching of
resources specified in command URIs.
This patch:
* Updates the Mesos shaded protobuf dependency to 0.23.0
* Allows setting `spark.mesos.fetchCache.enable` to enable the fetch cache for
all specified URIs. (URIs must be specified for the setting to have any affect)
* Updates documentation for Mesos configuration with the new setting.
This patch does NOT:
* Allow for per-URI caching configuration. The cache setting is global to ALL
URIs for the command.
