> Key: SPARK-16952
> URL: https://issues.apache.org/jira/browse/SPARK-16952
> Project: Spark
> Issue Type: Bug
> Components: Mesos, Scheduler
> Affects Versions: 1.5.2, 1.6.0, 1.6.1, 2.0.0
> Reporter: Charles Allen
> Priority: Minor
> Fix For: 2.1.0
>
>
> In the Mesos coarse grained scheduler, setting `spark.executor.uri` bypasses
> the code path which requires `spark.mesos.executor.home` since the uri
> effectively provides the executor home.
> But
> `org.apache.spark.scheduler.cluster.mesos.MesosCoarseGrainedSchedulerBackend#createCommand`
> requires `spark.mesos.executor.home` to be set regardless.
> Our workaround is to set `spark.mesos.executor.home=/dev/null` when using an
> executor uri.
