Stavros Kontopoulos commented on SPARK-20812:
---------------------------------------------
Spark-submit should store the keytab file in the secret store? Wouldn't be more
safe to avoid dispatcher knowing secrets or other info about the drivers it
launches? Is there a design doc for this?
> Add Mesos Secrets support to the spark dispatcher
> -------------------------------------------------

> Key: SPARK-20812
> URL: https://issues.apache.org/jira/browse/SPARK-20812
> Project: Spark
> Issue Type: New Feature
> Components: Mesos
> Affects Versions: 2.3.0
> Reporter: Michael Gummelt
>
> Mesos 1.4 will support secrets. In order to support sending keytabs through
> the Spark Dispatcher, or any other secret, we need to integrate this with the
> Spark Dispatcher.
> The integration should include support for both file-based and env-based
> secrets.
