Soooo close. "schema registry is invalid because schema.name is set and
scheme registry is not..." paraphrasing a bit there. Looks like validation on
that is alittle buggy. I'm using the GrokReader without a schema registry set
and this is what pops up now. All else looks solid. Pretty sure this will
wrap it up.
