Re: Running Python Beam Functions on Spark Kubernetes Cluster

[Matthew K.]

Thanks Tom,

Looks like for Java, a standalone Job Service is not required to run beam functions on Spark, and spark-submit handles everything in cluster mode. But this is not the case for Python runner. Are you aware of any example in Python that runs in a (i.e. Kubernetes) cluster?

I spend a while figuring that out a week or two ago and wrote up a blog post on it: https://www.spicule.co.uk/news/post/2019-09-30-running-an-apache-beam-pipeline-over-spark-on-kubernetes

 

And some sample code here: https://gitlab.com/spiculedata/spark-beam-demo

 

 

The actual submit command looks something like this:

 

./spark-submit --master k8s://https:// --deploy-mode cluster --name spark-demo --class com.example.beam.ProcessHealth2 --conf spark.executor.instances=5 --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark  --conf spark.kubernetes.container.image=/spark: local:///opt/wordcount-app-1.0.0-shaded.jar "--runner=SparkRunner" "--awsKey=" "--awsSecret=" "--outputPath=s3:///" "--awsRegion=us-east-1”

I would like to run Beam functions on Spark cluster created on a Kubernetes using `spark-submit`. However, it is not clear how to integrate Beam's Job Service with non-standalone Spark master (on Kubernetes) launched by `spark-submit`.

 

Any information is appreciated.

 

Thanks
