Julien Aymé commented on MAHOUT-1100:
-------------------------------------
You're welcome. It was indeed an easy one. What is not easy is to prevent the
infinite loop in buildClusters (see the comment of the first test in the
attached test case). Do you have an idea of how to fix it? Maybe some checks
that no variable state has changed between two consecutive calls, and so it
will be stuck in the loop... I'll try to look into it later.
