I wanted to bring back to the community that there are two competing PRs on how classloaders are being used to detect which resources needed to run a pipeline: * https://github.com/apache/beam/pull/4497 * https://github.com/apache/beam/pull/4514
PR/4497 uses the fact that in JDK 9 doesn't use a URLClassLoader if its the system class loader anymore and relies on the parsing the standard JAVA_CLASS_PATH system property. PR/4514 uses ClassLoader#getResources to find all "" and "META-INF" resources and then finds the appropriate path based upon the resource. As a community we have two questions: 1) If they handle different use cases, should we have a configurable way in which a user can specify which resource detection strategy we go with? 2) Which one should we go with? (or both and which one is the default) I have added Liam and Romain the authors of the two PRs to the thread. Would you please provide an argument for the merits and drawbacks of your approach.
