ClassNotFoundException on remote cluster

[Abhishek Jain]

Hi,

I'm running into ClassNotFoundException only when I run my application on a standalone cluster (using flink cli). If i directly run the main class in my IDE, it's working fine.

I've copied the stacktrace from flink standalone session logs here.

How are you packaging the jar that you submit? Specifically, are you ensuring that all your classes are actually contained within?

This is a spring boot app that I've packaged using maven (Apache Maven 3.3.9). I've verified the class is present in the jar as well.

Also, the `execute()` call happens inside `MyWikiAnalysis` spring managed bean on PostConstruct but I don't think that should cause any issue. Any idea?

Let me know if you need more info on my environment.

Historically spring applications are not interacting well with Flink; we've had people run in these issues multiple times on the mailing lists. Unfortunately, I don't believe any committer has any real experience in this area; I'm afraid I can neither help you myself nor refer you to someone that could :/
