Sebastian Schelter commented on MAHOUT-1427:
--------------------------------------------
MatrixMultiplicationJob uses a mapside join via CompositeInputFormat. AFAIK
this is not available in the .mapreduce API of Hadoop 1.x, unfortunately. How
do we handle this situation, is there a viable alternative?
> Convert old .mapred API to new .mapreduce
