--------------------------------------------------------------
Matt, I believe Roman was aiming at contributors being able to mix and match
versions, not really users. I don't see how users would be able to do so and I
personnaly see Bigtop as a coherent stack instead of a kit to build stacks
(although nothing prevent anyone from selecting their own favourite downstream
versions).
Even if Bigtop would not specify any version in its dependencies sections,
there would still be work needed to make sure components compile against each
others (for instance, doing a maven build on hbase, would pull hadoop from its
default profile, not the one we want to exercise, so the way a component is
built may have to be tweaked) as well as testing their integration.
But mix-matching is only one of many benefits of such proposal.
