----------------------------------------------------------------

[~stack], do you want me to backport the large (and complete) patch from HBASE-8369 into 0.96,
or rather forward port the more minimal patch I have here for 0.94? The HBASE-8369 patch is
pretty invasive. For 0.94 I definitely prefer the smaller patch. 0.96, I can see going either
way. I'll make sure the M/R APIs are the same either way.

[~ndimiduk], even 0.98/trunk do not have a mapred version. We can file a separate issue to
add mapred support to all branches (or not, depending on discussion) for HIve support.

> I think we want drive towards all (or most) M/R over HBase to be against snapshots and
HDFS directly.
> Adopting a simple input format (even if just as a sample) as part of HBase will allow
us to direct users this way.
