Review comment:
@dongjoon-hyun this is required by the tests, so it could be just DEBUG
mode, disabled by default. It is not meant to be another feature and does no
harm. I want to debug the verbose output so tests in K8s can get the java
option values set in the driver. Is there another way to trigger this (beyond
writing a main that prints them and adding it to Spark examples package)?
