How to limit the number of retries on Spark job fa

Question

We are running a Spark job via spark-submit, and I can see that the job will be re-submitted in the case of failure.

How can I stop it from having attempt #2 in case of yarn container failure or whatever the exception be?

Answer 1

There are two settings that control the number of retries (i.e. the maximum number of ApplicationMaster registration attempts with YARN is considered failed and hence the entire Spark application):

• spark.yarn.maxAppAttempts - Spark's own setting. See MAX_APP_ATTEMPTS:

  private[spark] val MAX_APP_ATTEMPTS = ConfigBuilder("spark.yarn.maxAppAttempts")
    .doc("Maximum number of AM attempts before failing the app.")
    .intConf
    .createOptional
  

• yarn.resourcemanager.am.max-attempts - YARN's own setting with default being 2.

(As you can see in YarnRMClient.getMaxRegAttempts) the actual number is the minimum of the configuration settings of YARN and Spark with YARN's being the last resort.

Answer 2

An API/programming language-agnostic solution would be to set the yarn max attempts as a command line argument:

spark-submit --conf spark.yarn.maxAppAttempts=1 <application_name>

See @code 's answer

Answer 3

Add the property yarn.resourcemanager.am.max-attempts to your yarn-default.xml file. It specifies the maximum number of application attempts.
