             Summary: MesosClusterScheduler double-escapes parameters to bash command
                 Key: SPARK-23464
                 URL: https://issues.apache.org/jira/browse/SPARK-23464
             Project: Spark
          Issue Type: Bug
          Components: Mesos
    Affects Versions: 2.2.0
         Environment: Spark 2.2.0 with Mesosphere patches (but the problem exists in main repo)

DC/OS 1.9.5
            Reporter: Marcin Kurczych


Parameters passed to driver launching command in Mesos container are escaped using _shellEscape_ function. In SPARK-18114 additional wrapping in double quotes has been introduced. This cancels out quoting done by _shellEscape_ and makes in unable to run tasks with whitespaces in parameters, as they are interpreted as additional parameters to in-container spark-submit.

This is how parameter passed to in-container spark-submit looks like now:
{code}
--conf "spark.executor.extraJavaOptions="-Dfoo=\"first value\" -Dbar=another""
{code}

This is how they look after reverting SPARK-18114 related commit:
{code}
--conf spark.executor.extraJavaOptions="-Dfoo=\"first value\" -Dbar=another"
{code}

In current version submitting job with such extraJavaOptions causes following error:
{code}
Error: Unrecognized option: -Dfoo=another

Usage: spark-submit [options] <app jar | python file> [app arguments]
Usage: spark-submit --kill [submission ID] --master [spark://...]
Usage: spark-submit --status [submission ID] --master [spark://...]
Usage: spark-submit run-example [options] example-class [example args]

Options:
  --master MASTER_URL         spark://host:port, mesos://host:port, yarn, or local.
  --deploy-mode DEPLOY_MODE   Whether to launch the driver program locally ("client") or
                              on one of the worker machines inside the cluster ("cluster")
                              (Default: client).
