Zoraida Hidalgo Sanchez commented on MAHOUT-1231:
-------------------------------------------------
Lee, it happens to me when running reuters example(cluster-reuters.sh).
tfidf-vectors directory contains empty content and kmeans fails to pick up the
random clusters. It works if I run it in local mode. I am running 0.7 version
with claudera 1.4.2
> "No input clusters found in " error in kmeans
