Hi All,
I'm new to Mahout. I'm using the SpectralKMeansDriver.java example provided in
the Mahout library. The code works fine.
After code execution I want to find which IDs belong to which clusters.
I'm using the 'mahout clusterdump' command to dump the clusters and it dumps
the centroid, radius and points. but I can't find which ID belongs to which
cluster information.
I found the below snipnet in the code example 'SpectralKMeansDriver.java',
which I presume is looking for the input mapping file but how do can I provide
this from the command line. // Restore name to id mapping and read through
the cluster assignments Path mappingPath = new Path(new
Path(conf.get("hadoop.tmp.dir")), "generic_input_mapping"); List<String>
mapping = new ArrayList<>(); FileSystem fs =
FileSystem.get(mappingPath.toUri(), conf); if (fs.exists(mappingPath)) {
SequenceFile.Reader reader = new SequenceFile.Reader(fs, mappingPath, conf);
Text mappingValue = new Text(); IntWritable mappingIndex = new
IntWritable(); while (reader.next(mappingIndex, mappingValue)) {
String s = mappingValue.toString(); mapping.add(s); }
HadoopUtil.delete(conf, mappingPath); } else { log.warn("generic input
mapping file not found!"); }
Would appreciate any pointers.
Regards,Mitesh
