> Currently Crunch targets HBase 1.0. Certain vendors however are trying to
> maintain API compatibility with HBase 0.96, 0.98, 1.0, and all 1.x.
> While the API compatibility is ok across these versions, it was however not
> binary compatible as HBase changed the method signature from returning
> void[1] to returning OperationWithAttributes[1] (and in later versions Scan).
> This results in an exception like the following, when you try to use the
> latest Crunch 0.14 release against that vendor's distribution of HBase which
> we should be theoretically compatible with.
