Various properties files specify whirr.env.repo=cdh4
I try to use CDH3 by specifying whirr.env.repo=cdh3 (default is cdh4), but it doesn't work. Looking in the scripts, a variable $REPO is used, and specifying whirr.env.REPO=cdh3 (uppercase repo) makes it work for me.
Looking around, it seems whirr.env.repo got introduced in
WHIRR-415, and the usage of $REPO probably predates that.
I'm not entirely sure if the lowercase variant serves a purpose, I would guess it does otherwise
WHIRR-415 makes little sense.
Maybe someone can shine some light one this, and then we can adjust the sample/test properties files accordingly.
