Tom White commented on MAHOUT-950:
----------------------------------
As a sanity check for 0.20/1.x, I built Hadoop locally with the patch from
MAPREDUCE-3607 applied and changed the version of hadoop-core in the POM to
1.1.0-SNAPSHOT. Both LocalSSVDSolverDenseTest and
LocalSSVDSolverSparseSequentialTest passed.
> Change BtJob to use new MultipleOutputs API

> BtJob uses a mixture of the old and new MapReduce API to allow it to use
> MultipleOutputs (which isn't available in Hadoop 0.20/1.0). This fails when
> run against 0.23 (see MAHOUT-822), so we should change BtJob to use the new
> MultipleOutputs API. (Hopefully the new MultipleOutputs API will be made
> available in a 1.x release - see MAPREDUCE-3607.)
