Dense Matrix Storage

I think,... Current model seems not good fit with hbase/hadoop.
Value is a too small, needs a lot of columns as describe below.

           column
===============================
row1    column:1
           ....
           column:N

So, I propose that we store the vector instead of entry.

           vector
===============================
row1    vector:0   <1,2,3,4,....9999>
           vector:1   <9999,...   N>

What do you think?
