Marcin Kurczych created SPARK-23464:
---------------------------------------
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).
