SequenceFile.createWriter - throws FileNotFoundException
The following line in KMeansBSP.java throws the FileNotFoundException
SequenceFile.Writer centerWriter = SequenceFile.createWriter(fs,
        conf, center, VectorWritable.class, NullWritable.class,
        CompressionType.NONE);

I am getting the below exception message when I tried executing HAMA KMeans machine learning algorithm.
