I'm running the example in Eclipse using the stand-alone mode in the
hadoop-0.19.1 jar file. It works fine, as does the hadoop compile in
Eclipse. I cannot; however, get any hadoop stuff to work from the
command line. Even though my JAVA_HOME environment is set to /
Library/Java/Home and java -version yields:
Java(TM) SE Runtime Environment (build 1.6.0_07-b06-153)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_07-b06-57, mixed mode)
... the hadoop build script and the start-all.sh commands all
complain about class version errors. Can any other Mac users help me
out?

Yeah, what version of Hadoop are you running? I got it w/ 0.19.1,
but maybe I didn't set something up right.

Improving speed of KMeans
-------------------------
Key: MAHOUT-99
URL: https://issues.apache.org/jira/browse/MAHOUT-99
Project: Mahout
Issue Type: Improvement
Components: Clustering
Reporter: Pallavi Palleti
Assignee: Grant Ingersoll
Fix For: 0.1
Attachments: MAHOUT-99-1.patch, Mahout-99.patch,
MAHOUT-99.patch
Improved the speed of KMeans by passing only cluster ID from
mapper to reducer. Previously, whole Cluster Info as formatted
s`tring was being sent.
Also removed the implicit assumption of Combiner runs only once
approach and the code is modified accordingly so that it won't
create a bug when combiner runs zero or more than once.
