I just read the file and write it on disk. Its pretty easy.
FileStatus[] partFiles = getAllClusteredPointPartFiles();
for (FileStatus partFile : partFiles) {
SequenceFile.Reader clusteredPointsReader = new
SequenceFile.Reader(fileSystem, partFile.getPath(),
conf);
WritableComparable clusterIdAsKey = (WritableComparable)
clusteredPointsReader.getKeyClass()
.newInstance();
Writable vector = (Writable)
clusteredPointsReader.getValueClass().newInstance();
while (clusteredPointsReader.next(clusterIdAsKey, vector)) {
//use clusterId and vector here
}
clusteredPointsReader.close();
closeWriters();
}
}

Hi all,
I am new to Mahout.
I have successfully run kmeans in mahout using Synthetic Control Data.
I wish to see the mapping information present in clusteredPoints
directory.
Is there any way to extract the data present in clusteredPoints
directory to Text file
(as we do for the clusters directory using clusterdump tool)?
Anyhelp is appreciated.
Thank you,
Rachana
