Cluster 'names' are just numbers and these are allocated automatically.
NamedVectors can be used to assign meaningful identifiers (e.g. document
names) to input vectors but not to clusters. As clusters are produced
dynamically, I'm not sure how one could reliably assign meaningful
identifiers to them apriori. Wouldn't the name be derived by inspection
of the cluster centers after iterations complete?
Since you are clustering documents, perhaps you could post-process your
clusters using your dictionary to assign names based upon the largest n
terms in each cluster center vector. A 'NamedCluster' wrapper could then
preserve this information into subsequent clustering steps.

As far as I know, cluster names can not be changed.
However, there is a NamedVector which can be used to name vectors. Not
sure whether it can be used in this case.

Hi everyone,
for cluster dumping i am using that code:
-------------------------------------------------------------------------------------------------------------
bin/mahout clusterdump \
-d haberdata-vectorsall/dictionary.file-0 \
-dt sequencefile \
-s haberdata-kmeans-clustersall/clusters-10-final/part-r-00000 \
-n 20 \
-b 100 \
-p haberdata-kmeans-clustersall/clusteredPoints/\
-o outputall/outFromIdea_kmeansWithEuclidean.txt\
-of TEXT
-------------------------------------------------------------------------------------------------------------
this code gives an output like this :
----------------------------------------------------------------------------------------------------------------

i want to ask a question.Can i rename my cluster names.For example in
this example my cluster name is VL-3104 , and i want to rename this
name with words that represent my cluster the best.
Sorry for my English.
Thanks.
