Hi, I need to use hbase to 1) store two sparse matrices. 2) Write a mapreduce program to multiply them.
Problem 1: How do I create a table for sparse matrices in hbase and then pass it to a mapreduce application? Problem 2: The problem that I face is that the examples of mapper functions that I have seen - wordcount etc only look at one data item at a time and produce the key-value pair. How do I look at more than one item at a time to produce a key-value pair?
