Review comment:
No, actually you're right. Yes, seems after Scala tests here, the PATH and
JAVA_HOME set as are.
I thought:
https://github.com/apache/spark/blob/209b9361ac8a4410ff797cff1115e1888e2f7e66/python/pyspark/java_gateway.py#L45-L60
https://github.com/apache/spark/blob/3cb82047f2f51af553df09b9323796af507d36f8/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L425
Here somehow happened to use JDK 8.
Actually the PySpark tests and SparkR tests passed at
https://github.com/apache/spark/pull/25443#issuecomment-522206143
So, the issue persists here .. but I guess yes we can do it separately since
at least this PR _seems_ setting JDK 11 correctly, and it virtually doesn't
affect any main or test code (if this title is not used).
