Hyukjin Kwon resolved SPARK-12943.
----------------------------------
Resolution: Incomplete
> spark should distribute truststore if used in yarn-cluster mode
> ---------------------------------------------------------------
>
> Key: SPARK-12943
> URL: https://issues.apache.org/jira/browse/SPARK-12943
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 1.5.2
> Reporter: John Vines
> Priority: Major
> Labels: bulk-closed
>
> spark.ssl.trustStore is used to specify the truststore to use for SSL. It is
> described somewhat at
> http://spark.apache.org/docs/1.5.2/configuration.html#security
> What it does not specify is that, when used in yarn environments, it must be
> an absolute path available on all nodes.
> In an ideal world, it would recognize it's in yarn-cluster mode, put that
> file in the distributed cache, and then update the local conf in each
> driver/executor to the local path to use they're local version.
> Or at the very least, the docs could be clearer that it's incompatible with
> yarn-cluster mode unless you give it a path that's available on all nodes.
