Hi All,

 

Just updated by trunk today getting below error while running cluster-dump.

 

./bin/mahout clusterdump -s examples/bin/work/reuters-kmeans/clusters-10 -d
examples/bin/work/reuters-out-seqdir-sparse/dictionary.file-0 -dt
sequencefile -b 100 -n 20 -o output.txt -p
examples/bin/work/reuters-kmeans/clusteredPoints
