Temat: Re: How to list all vectors from a cluster

Hi

that work for me
  ...
Path path = new Path(workPath + kmeansClustersPath + 
"/clusteredPoints/part-m-0");
for (Pair<IntWritable, WeightedVectorWritable> record : new 
SequenceFileDirIterable<IntWritable, WeightedVectorWritable>(path, 
PathType.GLOB,
                 PathFilters.logsCRCFilter(), conf)) {
             NamedVector vec = ((NamedVector) 
record.getSecond().getVector());
             System.out.println(record.getFirst().get() + "  " + 
vec.getName());

         }
...
