Robert Metzger commented on FLINK-6031:
---------------------------------------
I responded on the BEAM issue.
Back to this one:
>From the ML discussion, it seems that we need to have the following three
>options for controlling the user jar inclusion:
- "user code first" or "user code last" in the classpath
- no user code in the classpath
> 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.
