Hudson commented on MAHOUT-749:
-------------------------------
Integrated in Mahout-Quality #953 (See
[https://builds.apache.org/job/Mahout-Quality/953/])
MAHOUT-749: Implemented multiple reducer approach from Jira patch, plus a
scalability enhancement to avoid accumulating merged clusterIds if -cl option
is not present. The defaults are for the same behavior as before. All tests
run though this needs more testing to see how it really scales
