Hi vino,
Yes, I’m trying to set Java 8 environment for Flink job, but YARN is running on
Java 7 which I can’t change.

Hi Paul,
This exception means that the jdk version of the execution code is lower
than the compiled jdk version.

pass the JAVA_HOME environment variable to YARN.
Am I missing something? And should I create an issue requesting for that?
Best,
Paul
