Overall lgtm, but you have a lot of excessive whitespaceing (look for the red in the review)

bq.  Review request for hbase.

bq.  Summary
bq.  -------
bq.  
bq.  Add API for atomic row mutations to HBase (currently Put and Delete).
bq.  
bq.  Client API would look like this:
bq.      Delete d = new Delete(ROW);
bq.      Put p = new Put(ROW);
bq.      ...
bq.      AtomicRowMutation arm = new AtomicRowMutation(ROW);
bq.      arm.add(p);
bq.      arm.add(d);
bq.      myHtable.atomicMutation(arm);
bq.  
bq.  
bq.  This addresses bug HBASE-3584.

 It would be nice to do that.
> It would also allow us to do a CAS where we could do a put/increment if the check succeeded.
