Nick Dimiduk commented on HBASE-9165:
-------------------------------------
Yes. This change is an effective noop; the same jar contains both classes. It's
value is to bring the implementations across branches back into sync.

>
> The way we support adding HBase dependencies to a MapReduce job in
> {{TableMapReduceUtils#addDependencyJars(job)}} is a bit monolithic. Advanced
> users need a way to add HBase and its dependencies to their job without us
> snooping around for ouput formats and the like (see PIG-3285). We can also
> benefit from a little more code reuse between our {{mapred}} and
> {{mapreduce}} namespaces.
