@the-other-tim-brown Thanks for the contribution, can you elaborate a little more why the CleanPlanner needs to be serializable?

Okay, it makes sense because it implements the Serializable interface.

@the-other-tim-brown Thanks for the contribution, can you elaborate a little more why the CleanPlanner needs to be serializable?

Okay, it makes sense because it implements the Serializable interface.

More specifically, it is referenced from a lambda function passed to the Hoodiecontext.map so it needs to be serialized then.
