stack updated HBASE-1385:
-------------------------

    Attachment: mr.patch

This patch makes number of splits equal the number of regions in the table.

I was going to update to new MR API too but I then started thinking that we can live w/ the deprecated through 0.20.0.

And then I thought that all this stuff is going to have to change to suit the new API -- e.g. Result instead of RowResult and Put or Delete instead of BatchUpdate -- etc.

So, going to wait on this one.  I think we need to discuss what we want to do for 0.20.0.  We could leave this stuff as is and make a new package named mapreduce that has in it the new versions of these classes to match what is happening up in hadoop (new classes are in the mapreduce package rather than in mapred).
