Guowei Ma commented on FLINK-13840:
-----------------------------------
As Till said, it is an easy way to add a different directory than lib to
PackagedProgram.
I wrote a draft doc about how to deal with this.
Any comments are welcome!

> Let StandaloneJobClusterEntrypoint use user code class loader
> -------------------------------------------------------------
>
> Key: FLINK-13840
> URL: https://issues.apache.org/jira/browse/FLINK-13840
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.9.0, 1.10.0
> Reporter: Till Rohrmann
> Priority: Major
> Fix For: 1.10.0
>
>
> In order to resolve class loading issues when using the
> {{StandaloneJobClusterEntryPoint}}, it would be better to run the user code
> in the user code class loader which supports child first class loading. At
> the moment, the user code jar is part of the system class path and, hence,
> part of the system class loader.
> An easy way to solve this problem would be to place the user code in a
> different directory than {{lib}} and then specify this path as an additional
> classpath when creating the {{PackagedProgram}}.
