Description

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.
