Hi,
I want to use ClusteringUtils on Kmeans clusteredPoints to get
summarizeClusterDistances , daviesBouldinIndex dunnIndex
Is there any sample or example how to use these features?

U could call ClusterQualitySummarizer which then calls ClusteringUtils to spew
out the different metrics u had specified.
For an example, see the Streaming Kmeans section in
examples/bin/cluster-reuters.sh.
It calls 'qualcluster' with options -i tf-idf vectors generated from
seq2sparse -c
OK I found that I have to add this property to mapred-site.xml
property
namemapred.child.java.opts/name
value-Xmx2048m/value
/property

Darn. U r the second guy to report that this week. Change that line to what
ted suggested. The issue is with guava incompatibility with Hadoop's
antiquated guava version.

Just FYI... downgrading guava to 11.0.2 has fixed the build error in
mahout-math as suggested by Ted however it is causing some other build
error in mahout-core

Hello,
I just posted an article on Comparing Document Classification Functions
of Lucene and Mahout.
I usually do try and error. Start with some very large value and do a

Mahmood,
Firstly thanks for starting this email thread and for
highlighting the issues with wikipedia example. Since you raised this issue, I
updated the new wikipedia examples page at

and also responded to a similar
Thinking loud here. If this is indeed a build error that u r seeing, a better
fix would be to exclude hadoop's guava 11 transitive dependency in the pom as
opposed to having downgrade Mahout code to be guava 11 compatible.
We might have missed excluding Hadoop's Guava 11 jar during the recent
Cool, thanks Sebastian!
