Thanks @dongjoon-hyun for reviewing this PR. spark.driver.extraJavaOptions and spark.executor.extraJavaOptions could be a workaround. However, it should not be a long term solution, right? Customer already specified spark.driver.cores and spark.executor.cores and we should honor it. I don't know which spark version target java 8u191 and above, and we should put the fix in for such spark version in the future then.
