Is there a way to submit spark job on different server running master

We have a requirement to schedule spark jobs, since we are familiar with apache-airflow we want to go ahead with it to create different workflows. I searched web but did not find a step by step guide to schedule spark job on airflow and option to run them on different server running master.

Answer to this will be highly appreciated. Thanks in advance.

We can use any of these below options to submit the spark job in Airflow

  1. SparkSubmitOperator.
  2. PythonOperator
  3. BashOperator

Below is the link which explains us with the code for running the airflow using these jobs https://medium.com/codex/executing-spark-jobs-with-apache-airflow-3596717bbbe3

There are 3 ways you can submit Spark jobs using Apache Airflow remotely:

(1) Using SparkSubmitOperator: This operator expects you have a spark-submit binary and YARN client config setup on our Airflow server. It invokes the spark-submit command with given options, blocks until the job finishes and returns the final status. The good thing is, it also streams the logs from the spark-submit command stdout and stderr.

You really only need to configure a yarn-site.xml file, I believe, in order for spark-submit --master yarn --deploy-mode client to work.

Once an Application Master is deployed within YARN, then Spark is running locally to the Hadoop cluster.

If you really want, you could add a hdfs-site.xml and hive-site.xml to be submitted as well from Airflow (if that's possible), but otherwise at least hdfs-site.xml files should be picked up from the YARN container classpath

(2) Using SSHOperator: Use this operator to run bash commands on a remote server (using SSH protocol via paramiko library) like spark-submit. The benefit of this approach is you don't need to copy the hdfs-site.xml or maintain any file.

(3) Using SimpleHTTPOperator with Livy: Livy is an open source REST interface for interacting with Apache Spark from anywhere. You just need to have REST calls.

I personally prefer SSHOperator :)
