The key in the CSV is the clusterId (and not the named vector).
Here's the complete code snippet which should make sense.
{Code}
Cluster cluster = clusterWritable.getValue();
line.append(cluster.getId());
List<WeightedPropertyVectorWritable> points =
getClusterIdToPoints().get(cluster.getId());
if (points != null) {
for (WeightedPropertyVectorWritable point : points) {
Vector theVec = point.getVector();
line.append(',');
if (theVec instanceof NamedVector) {
line.append(((NamedVector)theVec).getName());
} else {
String vecStr = theVec.asFormatString();
//do some basic manipulations for display
vecStr = VEC_PATTERN.matcher(vecStr).replaceAll("_");
line.append(vecStr);
}
}
getWriter().append(line).append("\n");
}
{Code}
For each clusterId it prints the names of the Named Vectors in the cluster or
the vector itself (if not a named vector).
Hope that clarifies.

Suneel,
I was going through code of CSVClusterWriter and found that if
vector
is an instance of NamedVector then it writes only Key.
if (theVec instanceof NamedVector) {
line.append(((NamedVector)theVec).getName());
} else {
String vecStr = theVec.asFormatString();
//do some basic manipulations for display
vecStr = VEC_PATTERN.matcher(vecStr).replaceAll("_");
line.append(vecStr);
}
Hence I am getting only key as an ouput of cluster dumper. Request you
to specify the design assumption behind this....
