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.
