This looks like a bug. Can you open an issue for that? I will look into
it later.

Hey,
I get a weird error when I try to execute my job on the cluster. Locally
this works fine but running it from the command line fails during
typeextraction:
input1.union(input2, input3).map(Either::<UserEvent, Long>
Left).returns(eventOrLongType);
This fails when trying to extract the output type from the mapper, but I
wouldnt actually care about that because I am providing my custom type
implementation for this Either type.
The error:
