I'm experiencing with Spark (2.3.0) over Kubernetes in the past few days.

I've tested the example SparkPi from both linux and windows machines and found the linux spark-submit to run ok and give my proper results (spoiler: Pi is roughly 3.1402157010785055)
while on windows spark fails with class path issues (Could not find or load main class org.apache.spark.examples.SparkPi)

I've noticed that when running spark-submit from linux the classpath looks like that:
-cp ':/opt/spark/jars/*:/var/spark-data/spark-jars/spark-examples_2.11-2.3.0.jar:/var/spark-data/spark-jars/spark-examples_2.11-2.3.0.jar'

While on windows, the logs show a bit different version:
-cp ':/opt/spark/jars/*:/var/spark-data/spark-jars/spark-examples_2.11-2.3.0.jar;/var/spark-data/spark-jars/spark-examples_2.11-2.3.0.jar'

Note the : vs. ; in the classpath which I think is the cause for this issue.

Suggestions how to spark-submit from windows machine without the classpath issue?

This is our spark-submit command:

bin/spark-submit \ --master k8s://https://xxx.xxx.xxx.xxx:6443 \ --deploy-mode cluster \ --name spark-pi \ --class org.apache.spark.examples.SparkPi \ --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark \ --conf spark.driver.memory=1G \ --conf spark.driver.cores=1 \ --conf spark.executor.instances=5 \ --conf spark.executor.cores=1 \ --conf spark.executor.memory=500m \ --conf spark.kubernetes.container.image=spark:2.3.0 \ http://xxx.xxx.xxx.xxx:9080/spark-examples_2.11-2.3.0.jar

Thanks
