[bitnami/spark] Getting java.io.InvalidClassException: org.apache.spark.rpc.netty.RpcEndpointVerifier$CheckExistence; local class incompatible with matching versions

[Bassadin]

Name and Version

bitnami/spark:3.2.2

What steps will reproduce the bug?

1. Clone https://github.com/Bassadin/Informationssysteme-INM2/tree/fff8fb24922224cfcf4a86cd6c359009fa77ec4c/Task_03
2. Start the docker-compose containers (docker-compose up -d)
3. Install SBT dependencies
4. Run main function of class A03_ParseJsonMain (the JSON file being loaded is not in the repo, but it fails before the JSON parsing anyway)

What is the expected behavior?

I expected the connection to Spark to work

What do you see instead?

I see the following error:

It seems a very specific use case difficult to reproduce on our side and very tied to your scenario.

For information regarding the application itself, customization of the content within the application, or questions about the use of the technology or infrastructure; we highly recommend checking forums and user guides made available by the project behind the application or the technology.

That said, we will keep this ticket open until the stale bot closes it just in case someone from the community adds some valuable info.

@carrodher Thanks for your reply :) I guess I'll try asking else where, then. Thanks for keeping the issue open anyway, too.

This Issue has been automatically marked as "stale" because it has not had recent activity (for 15 days). It will be closed if no further activity occurs. Thanks for the feedback.

[github-actions]

Due to the lack of activity in the last 5 days since it was marked as "stale", we proceed to close this Issue. Do not hesitate to reopen it later if necessary.

I get this error when the client code is using Scala 2.13. The docker container is using Spark 2.12. This means the serialVersionUID will be different. Downgrade your client to using Scala 2.12 or use a container that runs Spark with Scala 2.13, I guess.
