Hi Wei Zhang, Can you check whether this path exists in your Hadoop HDFS /tmp/mahout-work-weiz/reuters-kmeans-clusters/part-randomSeed
Instead of using cluster_reuters.sh script file can you run Kmeans manually on your cluster. BTW, what is the command you are using for running cluster_reuters.sh script? Best, Mahesh.B.
