> Mesos scheduler does not respect spark.executor.extraClassPath configuration
> ----------------------------------------------------------------------------
>
> Key: SPARK-20814
> URL: https://issues.apache.org/jira/browse/SPARK-20814
> Project: Spark
> Issue Type: Bug
> Components: Mesos
> Affects Versions: 2.2.0
> Reporter: Gene Pang
> Priority: Critical
>
> When Spark executors are deployed on Mesos, the Mesos scheduler no longer
> respects the "spark.executor.extraClassPath" configuration parameter.
> MesosCoarseGrainedSchedulerBackend used to use the environment variable
> "SPARK_CLASSPATH" to add the value of "spark.executor.extraClassPath" to the
> executor classpath. However, "SPARK_CLASSPATH" was deprecated, and was
> removed in this commit
> [https://github.com/apache/spark/commit/8f0490e22b4c7f1fdf381c70c5894d46b7f7e6fb#diff-387c5d0c916278495fc28420571adf9eL178].
> This effectively broke the ability for users to specify
> "spark.executor.extraClassPath" for Spark executors deployed on Mesos.
