hmm, yes, I create the patch by 'svn diff'. I also update my code reposity and create a new

> Defaultly, we don't know how to get progress during MR over a HBase table.
> But in a matrix, the data are sorted by row-no. we know the rows of a split of a HBase
table.
> we can compute *progress* by <no. row processed> / <total rows of the split>.
> And this is helpful that we can know the progress during blocking, multiplication and
other operations.
