Spark Configuration Properties

Spark configuration properties are generally applicable to the Nomad integration. The properties listed below are specific to running Spark on Nomad. Configuration properties can be set by adding --conf [property]=[value] to the spark-submit command.

• spark.nomad.cluster.expectImmediateScheduling (bool: false) - Specifies that spark-submit should fail if Nomad is not able to schedule the job immediately.

• spark.nomad.cluster.monitorUntil (string: "submitted") - Specifies the length of time that spark-submit should monitor a Spark application in cluster mode. When set to submitted, spark-submit will return as soon as the application has been submitted to the Nomad cluster. When set to scheduled, spark-submit will return as soon as the Nomad job has been scheduled. When set to complete, spark-submit will tail the output from the driver process and return when the job has completed.

• spark.nomad.datacenters (string: dynamic) - Specifies a comma-separated list of Nomad datacenters to use. This property defaults to the datacenter of the first Nomad server contacted.

• spark.nomad.docker.email (string: nil) - Specifies the email address to use when downloading the Docker image specified by spark.nomad.dockerImage. See the Docker driver authentication docs for more information.

• spark.nomad.docker.password (string: nil) - Specifies the password to use when downloading the Docker image specified by spark.nomad.dockerImage. See the Docker driver authentication docs for more information.

• spark.nomad.docker.serverAddress (string: nil) - Specifies the server address (domain/IP without the protocol) to use when downloading the Docker image specified by spark.nomad.dockerImage. Docker Hub is used by default. See the Docker driver authentication docs for more information.

• spark.nomad.docker.username (string: nil) - Specifies the username to use when downloading the Docker image specified by spark.nomad.dockerImage. See the Docker driver authentication docs for more information.

• spark.nomad.dockerImage (string: nil) - Specifies the URL for the Docker image to use to run Spark with Nomad's docker driver. When not specified, Nomad's exec driver will be used instead.

• spark.nomad.driver.cpu (string: "1000") - Specifies the CPU in MHz that should be reserved for driver tasks.

• spark.nomad.driver.logMaxFileSize (string: "1m") - Specifies the maximum size by time that Nomad should use for driver task log files.

• spark.nomad.driver.logMaxFiles (string: "5") - Specifies the number of log files that Nomad should keep for driver tasks.

• spark.nomad.driver.networkMBits (string: "1") - Specifies the network bandwidth that Nomad should allocate to driver tasks.

• spark.nomad.driver.retryAttempts (string: "5") - Specifies the number of times that Nomad should retry driver task groups upon failure.

• spark.nomad.driver.retryDelay (string: "15s") - Specifies the length of time that Nomad should wait before retrying driver task groups upon failure.

• spark.nomad.driver.retryInterval (string: "1d") - Specifies Nomad's retry interval for driver task groups.

• spark.nomad.executor.cpu (string: "1000") - Specifies the CPU in MHz that should be reserved for executor tasks.

• spark.nomad.executor.logMaxFileSize (string: "1m") - Specifies the maximum size by time that Nomad should use for executor task log files.

• spark.nomad.executor.logMaxFiles (string: "5") - Specifies the number of log files that Nomad should keep for executor tasks.

• spark.nomad.executor.networkMBits (string: "1") - Specifies the network bandwidth that Nomad should allocate to executor tasks.

• spark.nomad.executor.retryAttempts (string: "5") - Specifies the number of times that Nomad should retry executor task groups upon failure.

• spark.nomad.executor.retryDelay (string: "15s") - Specifies the length of time that Nomad should wait before retrying executor task groups upon failure.

• spark.nomad.executor.retryInterval (string: "1d") - Specifies Nomad's retry interval for executor task groups.

• spark.nomad.job (string: nil) - Specifies the Nomad job name.

• spark.nomad.job.template (string: nil) - Specifies the path to a JSON file containing a Nomad job to use as a template. This can also be set with spark-submit's --nomad-template parameter.

• spark.nomad.priority (string: nil) - Specifies the priority for the Nomad job.

• spark.nomad.region (string: dynamic) - Specifies the Nomad region to use. This property defaults to the region of the first Nomad server contacted.

• spark.nomad.shuffle.cpu (string: "1000") - Specifies the CPU in MHz that should be reserved for shuffle service tasks.

• spark.nomad.shuffle.logMaxFileSize (string: "1m") - Specifies the maximum size by time that Nomad should use for shuffle service task log files..

• spark.nomad.shuffle.logMaxFiles (string: "5") - Specifies the number of log files that Nomad should keep for shuffle service tasks.

• spark.nomad.shuffle.memory (string: "256m") - Specifies the memory that Nomad should allocate for the shuffle service tasks.

• spark.nomad.shuffle.networkMBits (string: "1") - Specifies the network bandwidth that Nomad should allocate to shuffle service tasks.

• spark.nomad.sparkDistribution (string: nil) - Specifies the location of the Spark distribution archive file to use.

• spark.nomad.tls.caCert (string: nil) - Specifies the path to a .pem file containing the certificate authority that should be used to validate the Nomad server's TLS certificate.

• spark.nomad.tls.cert (string: nil) - Specifies the path to a .pem file containing the TLS certificate to present to the Nomad server.

• spark.nomad.tls.trustStorePassword (string: nil) - Specifies the path to a .pem file containing the private key corresponding to the certificate in spark.nomad.tls.cert.
