A good and popular tool to help you with these kind of issues is the Dataflow diagram on our GitHub wiki.
I am assuming that this is still the same error as from the first post, please correct me if that is not the case.
The error seems to indicate something went wrong with the EMR job. The first thing I would try is, as per the diagram, to empty the
enriched:good files and rerun EmrEtlRunner with the
--skip staging option.
Step failures sometimes happen and restarting from the correct step and in the correct way (please see the recovery steps below the image) is sometimes required.
