How to submit PySpark job on Kubernetes (minikube) using spark-submit

5/10/2020

I have a PySpark job present locally on my laptop. If I want to submit it on my minikube cluster using spark-submit, any idea how to pass the python file ?

I'm using following command, but it isn't working

./spark-submit \
        --master k8s://https://192.168.64.6:8443 \
        --deploy-mode cluster \
        --name amazon-data-review \
        --conf spark.kubernetes.namespace=jupyter \
        --conf spark.executor.instances=1 \
        --conf spark.kubernetes.driver.limit.cores=1 \
        --conf spark.executor.cores=1 \
        --conf spark.executor.memory=500m \
        --conf spark.kubernetes.container.image=prateek/spark-ubuntu-2.4.5 \
        --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark \
        --conf spark.kubernetes.container.image.pullPolicy=Always \
        --conf spark.kubernetes.container.image.pullSecrets=dockerlogin \
        --conf spark.eventLog.enabled=true \
        --conf spark.eventLog.dir=s3a://prateek/spark-hs/ \
        --conf spark.hadoop.fs.s3a.access.key=xxxxx \
        --conf spark.hadoop.fs.s3a.secret.key=xxxxx \
        --conf spark.hadoop.fs.s3a.impl=org.apache.hadoop.fs.s3a.S3AFileSystem \
        --conf spark.hadoop.fs.s3a.fast.upload=true \
        /Users/prateek/apache-spark/amazon_data_review.py

Getting following error -

python3: can't open file '/Users/prateek/apache-spark/amazon_data_review.py': [Errno 2] No such file or directory

Is it required to keep the file within the Docker image itself. Can't we run it locally by keeping it on laptop

Spark on Kubernetes doesn't support submitting locally stored files with spark-submit.

What you could do to make it work in cluster mode is to build Spark Docker image based on prateek/spark-ubuntu-2.4.5 with amazon_data_review.py put inside of it (eg using Docker COPY /Users/prateek/apache-spark/amazon_data_review.py /amazon_data_review.py statement).

Then just refer to it in the spark-submit command using local:// file system, eg.:

spark-submit \
  --master ... \
  --conf ... \
  ...
  local:///amazon_data_review.py

The alternative is to store that file on http(s):// or hdfs://-like accessible location.

It's solved. Running it with client mode helped to run it

--deploy-mode client
