Hoss: Thanks very much for your insight! Hmmm; this seems tractable. It could probably be addressed with a "urp phase" enum of sorts... and then splitting the DURP into some pieces that honor certain phases. I'm just thinking out loud here... I don't think I have time to undertake a large refactoring of this magnitude any way.
Do you know if DURP has functionality that can be used without SolrCloud other than the atomic updates feature?
