             Summary: Add parameter for per job yarn clusters to control 
whether the user code jar is included into the system classloader.
                 Key: FLINK-6031
                 URL: https://issues.apache.org/jira/browse/FLINK-6031
             Project: Flink
          Issue Type: Bug
          Components: YARN
            Reporter: Robert Metzger
            Priority: Critical


FLINK-4913 added the user jar into the system classloader, when starting a 
Flink per job YARN cluster.
Some users were experiencing issues with the changed behavior.

I suggest to introduce a new yarn specific configuration parameter (for the 
flink-conf.yaml file) to control if the user jar is added into system 
classloader.
