Yea, perhaps we just need the QA bot to be smart enough that it could handle
a cross-project patch attached to HADOOP? Maybe we do something crazy and
make a new HADOOPCROSS jira for patches that affect multiple projects? (just
brainstorming here...)

Right, that's the idea. You'd be added as a watcher (and get notified) for
any patch that touches the area you care about, regardless of whether it
also touches some other areas.
