How to list all vectors from a cluster

[Aleksander Sadecki]

Hi,

Thank you very much!

I am trying to implement a Java function with this class.

I wrote this piece of code:

                ClusterDumper dumper = new ClusterDumper(new Path(partMDir), 
new Path(
                                seqDir));

                Map<Integer, List<WeightedPropertyVectorWritable>> dumped = 
dumper
                                .getClusterIdToPoints();

                for (Integer numberOfList : dumped.keySet()) {
                        List<WeightedPropertyVectorWritable> listWithVectors = 
dumped
                                        .get(numberOfList);

                        for (WeightedPropertyVectorWritable vec : 
listWithVectors) {
                                System.out.println(vec.getVector().toString());
                        }
                }

when I run it, I have got an exception.

Constructor takes 2 parameters:

ClusterDumper(seqFileDir, pointsDir) and I do not know which files should I 
pass here...

I have got 9 files:

                String s1 = root + "synthetic_control.data";
                String s2 = root + "synthetic_control.seq";
                String s3 = root + ".synthetic_control.seq.crc";
                String s4 = outputDir + "\\clusteredPoints\\part-m-0";
                String s5 = outputDir + "\\clusteredPoints\\.part-m-0.crc";
                String s6 = outputDir + "\\clusters-0-final\\_policy";
                String s7 = outputDir + "\\clusters-0-final\\part-r-00000";
                String s8 = outputDir + "\\clusters-0-final\\._policy.crc";
                String s9 = outputDir + "\\clusters-0-final\\.part-r-00000.crc";

                Path p1 = new Path(s1);
                Path p2 = new Path(s2);
                Path p3 = new Path(s3);
                Path p4 = new Path(s4);
                Path p5 = new Path(s5);
                Path p6 = new Path(s6);
                Path p7 = new Path(s7);
                Path p8 = new Path(s8);
                Path p9 = new Path(s9);

I tried to find which 2 should I use but nothing works.

Some of them gives me:

synthetic_control.data not a SequenceFile

another one:

org.apache.hadoop.io.LongWritable cannot be cast to 
org.apache.hadoop.io.IntWritable

or sometimes there is no excpetion but output is empty.

Could you help me?

Thank you in advance
