== Spark Submit -- spark-submit shell script

spark-submit shell script allows you to manage your Spark applications.

You can <> to a Spark deployment environment for execution, <> or <> of Spark applications.

You can find spark-submit script in bin directory of the Spark distribution.

$ ./bin/spark-submit
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]

When executed, spark-submit script first checks whether SPARK_HOME environment variable is set and sets it to the directory that contains bin/spark-submit shell script if not. It then executes[spark-class shell script] to run <SparkSubmit standalone application>>.

CAUTION: FIXME Add Cluster Manager and Deploy Mode to the table below (see options value)

Refer to[Print Launch Command of Spark Scripts] (or[org.apache.spark.launcher.Main Standalone Application] where this environment variable is actually used).


Avoid using scala.App trait for a Spark application's main class in Scala as reported in[SPARK-4170 Closure problems when running Scala app that "extends App"].

Refer to <runMain internal method>> in this document.

=== [[prepareSubmitEnvironment]] Preparing Submit Environment -- prepareSubmitEnvironment Internal Method

[source, scala]

prepareSubmitEnvironment(args: SparkSubmitArguments) : (Seq[String], Seq[String], Map[String, String], String)

prepareSubmitEnvironment creates a 4-element tuple, i.e. (childArgs, childClasspath, sysProps, childMainClass).

.prepareSubmitEnvironment's Four-Element Return Tuple [cols="1,2",options="header",width="100%"] |=== | Element | Description | childArgs | Arguments | childClasspath | Classpath elements | sysProps |[Spark properties] | childMainClass | Main class |===

prepareSubmitEnvironment uses options to...


NOTE: prepareSubmitEnvironment is used in SparkSubmit object.

TIP: See the elements of the return tuple using <--verbose command-line option>>.

=== [[properties-file]] Custom Spark Properties File -- --properties-file command-line option

--properties-file [FILE]

--properties-file command-line option sets the path to a file FILE from which Spark loads extra[Spark properties].

TIP: Spark uses[conf/spark-defaults.conf] by default.

=== [[driver-cores]] Driver Cores in Cluster Deploy Mode -- --driver-cores command-line option

--driver-cores NUM

--driver-cores command-line option sets the number of cores to NUM for the[driver] in the[cluster deploy mode].

NOTE: --driver-cores switch is only available for cluster mode (for Standalone, Mesos, and YARN).

NOTE: It corresponds to[spark.driver.cores] setting.

NOTE: It is printed out to the standard error output in <>.

=== [[jars]] Additional JAR Files to Distribute -- --jars command-line option

--jars JARS

--jars is a comma-separated list of local jars to include on the driver's and executors' classpaths.


=== [[files]] Additional Files to Distribute --files command-line option

--files FILES


=== [[archives]] Additional Archives to Distribute -- --archives command-line option

--archives ARCHIVES


=== [[queue]] Specifying YARN Resource Queue -- --queue command-line option

--queue QUEUE_NAME

With --queue you can choose the YARN resource queue to[submit a Spark application to]. The yarn/[default queue name is default].

CAUTION: FIXME What is a queue?

NOTE: It corresponds to yarn/[spark.yarn.queue] Spark's setting.

TIP: It is printed out to the standard error output in <>.

=== [[actions]] Actions

==== [[submit]] Submitting Applications for Execution -- submit method

The default action of spark-submit script is to submit a Spark application to a deployment environment for execution.

TIP: Use <> command-line switch to know the main class to be executed, arguments, system properties, and classpath (to ensure that the command-line arguments and switches were processed properly).

When executed, spark-submit executes submit method.

[source, scala]

submit(args: SparkSubmitArguments): Unit

If proxyUser is set it will...FIXME

CAUTION: FIXME Review why and when to use proxyUser.

It passes the execution on to <>.

===== [[runMain]] Executing Main -- runMain internal method

[source, scala]

runMain( childArgs: Seq[String], childClasspath: Seq[String], sysProps: Map[String, String], childMainClass: String, verbose: Boolean): Unit

runMain is an internal method to build execution environment and invoke the main method of the Spark application that has been submitted for execution.

NOTE: It is exclusively used when <>.

When verbose input flag is enabled (i.e. true) runMain prints out all the input parameters, i.e. childMainClass, childArgs, sysProps, and childClasspath (in that order).

Main class:
[childArgs one per line]
System properties:
[sysProps one per line]
Classpath elements:
[childClasspath one per line]

NOTE: Use spark-submit's <> to enable verbose flag.

runMain builds the context classloader (as loader) depending on spark.driver.userClassPathFirst flag.

CAUTION: FIXME Describe spark.driver.userClassPathFirst

It <> specified in childClasspath input parameter to the context classloader (that is later responsible for loading the childMainClass main class).

NOTE: childClasspath input parameter corresponds to <> with the primary resource if specified in[client deploy mode].

It sets all the system properties specified in sysProps input parameter (using Java's[System.setProperty] method).

It creates an instance of childMainClass main class (as mainClass).

NOTE: childMainClass is the main class spark-submit has been invoked with.

TIP: Avoid using scala.App trait for a Spark application's main class in Scala as reported in[SPARK-4170 Closure problems when running Scala app that "extends App"].

If you use scala.App for the main class, you should see the following warning message in the logs:

Warning: Subclasses of scala.App may not work correctly. Use a main() method instead.

Finally, runMain executes the main method of the Spark application passing in the childArgs arguments.

Any SparkUserAppException exceptions lead to System.exit while the others are simply re-thrown.

===== [[addJarToClasspath]] Adding Local Jars to ClassLoader -- addJarToClasspath internal method

[source, scala]

addJarToClasspath(localJar: String, loader: MutableURLClassLoader)

addJarToClasspath is an internal method to add file or local jars (as localJar) to the loader classloader.

Internally, addJarToClasspath resolves the URI of localJar. If the URI is file or local and the file denoted by localJar exists, localJar is added to loader. Otherwise, the following warning is printed out to the logs:

Warning: Local jar /path/to/fake.jar does not exist, skipping.

For all other URIs, the following warning is printed out to the logs:

Warning: Skip remote jar hdfs://fake.jar.

NOTE: addJarToClasspath assumes file URI when localJar has no URI specified, e.g. /path/to/local.jar.

CAUTION: FIXME What is a URI fragment? How does this change re YARN distributed cache? See Utils#resolveURI.

==== [[kill]] Killing Applications -- --kill command-line option


==== [[status]][[requestStatus]] Requesting Application Status -- --status command-line option

=== [[driver-class-path]] --driver-class-path command-line option

--driver-class-path command-line option sets the extra class path entries (e.g. jars and directories) that should be added to a driver's JVM.

TIP: You should use --driver-class-path in client deploy mode (not[SparkConf]) to ensure that the CLASSPATH is set up with the entries. client deploy mode uses the same JVM for the driver as spark-submit's.

--driver-class-path sets the internal driverExtraClassPath property (when[SparkSubmitArguments.handle] called).

It works for all cluster managers and deploy modes.

If driverExtraClassPath not set on command-line, the[spark.driver.extraClassPath] setting is used.

NOTE: Command-line options (e.g. --driver-class-path) have higher precedence than their corresponding Spark settings in a Spark properties file (e.g. spark.driver.extraClassPath). You can therefore control the final settings by overriding Spark settings on command line using the command-line options.

.Spark Settings in Spark Properties File and on Command Line [options="header",width="100%"] |=== | Setting / System Property | Command-Line Option | Description |[spark.driver.extraClassPath] | --driver-class-path | Extra class path entries (e.g. jars and directories) to pass to a driver's JVM. |===

=== [[version]] Version -- --version command-line option

Type --help for more information.

=== [[verbose-mode]] Verbose Mode -- --verbose command-line option

When spark-submit is executed with --verbose command-line option, it enters verbose mode.

In verbose mode, the parsed arguments are printed out to the System error output.


It also prints out propertiesFile and the properties from the file.


=== [[deploy-mode]] Deploy Mode -- --deploy-mode command-line option

You use spark-submit's --deploy-mode command-line option to specify the[deploy mode] for a Spark application.

=== [[environment-variables]] Environment Variables

The following is the list of environment variables that are considered when command-line options are not specified:

  • MASTER for --master
  • SPARK_DRIVER_MEMORY for --driver-memory
  • SPARK_EXECUTOR_MEMORY (see[Environment Variables] in the SparkContext document)

=== External packages and custom repositories

The spark-submit utility supports specifying external packages using Maven coordinates using --packages and custom repositories using --repositories.

./bin/spark-submit \
  --packages my:awesome:package \
  --repositories s3n://$aws_ak:$aws_sak@bucket/path/to/repo

FIXME Why should I care?

=== [[main]] Launching SparkSubmit Standalone Application -- main method

TIP: The source code of the script lives in

When executed, spark-submit script simply passes the call to[spark-class] with org.apache.spark.deploy.SparkSubmit class followed by command-line arguments.


spark-class uses the class name -- org.apache.spark.deploy.SparkSubmit -- to parse command-line arguments appropriately.

Refer to[org.apache.spark.launcher.Main Standalone Application]

It creates an instance of[SparkSubmitArguments].

If in <>, it prints out the application arguments.

It then relays the execution to <> (with the application arguments):

  • When no action was explicitly given, it is assumed <> action.
  • <> (when --kill switch is used)
  • <> (when --status switch is used)

NOTE: The action can only have one of the three available values: SUBMIT, KILL, or REQUEST_STATUS.

==== [[sparkenv]] - load additional environment settings

  • consists of environment settings to configure Spark for your site.

export JAVA_HOME=/your/directory/java export HADOOP_HOME=/usr/lib/hadoop export SPARK_WORKER_CORES=2 export SPARK_WORKER_MEMORY=1G

  • is loaded at the startup of Spark's command line scripts.
  • SPARK_ENV_LOADED env var is to ensure the script is loaded once.
  • SPARK_CONF_DIR points at the directory with or $SPARK_HOME/conf is used.
  • is executed if it exists.
  • $SPARK_HOME/conf directory has file that serves as a template for your own custom configuration.

Consult[Environment Variables] in the official documentation.
