I see, this declaration is just there to make zookeeper "provided" in order
to not conflict with a cluster's copy/version of ZK from Hadoop. Hadoop version
kind of matters in that sense. I wonder if this is actually best left
unspecified then, since there is no intent to enforce any particular version of
ZK, just make sure it is not in the artifact when built with this profile?
