I already generated points directory when i run cluster (kmeans in my case).
But for the moment I can't generate clustedump because of error on this line:
ClusterDumper.readPoints(new Path("output/kmeans/clusters-0"), 2, conf);
Second parameter is double but he wants int but does not accept int .... well
pretty confused ...

Hello,
Clusterdump actually shows you the top terms and vectors of centroid and each
document. But to identify what vectors are for your document, You need to
generate points directory when running clustering algorithm and use the points
directory generated in the above step when generating cluster dump.
Thanks,
Kiran Bushireddy.
