Aaron Kimball commented on MAPREDUCE-2301:
------------------------------------------
+1 Changes look reasonable.
FWIW, I don't think this is going to entirely solve your problem. {{TestDBJob}}
should fail for the exact same reason -- it runs the job specified in
{{DBCountPageView.java}} under {{src/examples}}. So you might need to
parameterize the {{DB_URL}} in that process as well and make embedded server
hosting conditional on its value. (If TestDDDBIF fails and TestDBJob doesn't...
that's something else worth pondering.)
