Robert Metzger commented on FLINK-924:
--------------------------------------
I would go for white-listing the package that contains the user code and add a API for the user to add additional packages to the whitelist.
> Extend JarFileCreator to automatically include dependencies

> Key: FLINK-924
> URL:
https://issues.apache.org/jira/browse/FLINK-924> Project: Flink
> Issue Type: Improvement
> Reporter: Ufuk Celebi
> Assignee: Mingliang Qi
> Priority: Minor
>
> We have a simple {{JarFileCreator}}, which allows to add classes to a JAR file as follows:
> {code:java}
> JarFileCreator jfc = new JarFileCreator(jarFile);
> jfc.addClass(X.class);
> jfc.addClass(Y.class);
> jfc.createJarFile();
> {code}
> The created file can then be used with the remote execution environment, which requires a JAR file to ship.
> I propose the following improvement: use [ASM|
http://asm.ow2.org/] to extract all dependencies and add create the JAR file automatically.
> There is an [old tutorial|
http://asm.ow2.org/doc/tutorial-asm-2.0.html] (for ASM 2), which implements a {{DependencyVisitor}}. Unfortuneately the code does not directly work with ASM 5, but it should be a good starting point.
