Other folks on the list are also having this problem with the progressable utile exception & job failures. I don't know much about master compute usage but if it is needed to make the aggregators work, maybe we should have a default dummy class that just handles aggregators if no other master compute is specified? Or a wiki page? The progressable error message does not lead us to this conclusion directly.
