linux - 如何使用 Mahout kmeans 算法将集群转储到本地文件系统

Question

我已经按照此( http://sujitpal.blogspot.in/2012/09/learning-mahout-clustering.html )链接创建了初始集群和 k-means 集群，如下面的链接所述，但是当我尝试将集群转储到本地系统时，出现以下错误

转储集群的命令

mahout clusterdump -i kmeans-clusters -d vectorfiles/dictionary.file-* -dt seqfiles -n 10 -o cluster.txt

请建议我如何获得这个

谢谢

Answer 1

我使用了下面的命令及其工作原理

mahout clusterdump -dt sequencefile -d vectorfiles/dictionary.file-0 -i kmeans-clusters/clusters-1-final -o result.txt -b 10 -n 10
