大家好，我正在尝试为 k-mean 聚类算法运行集群转储。它不工作。任何的想法？这是来自 psudo 模式集群上 Mahout in Action 的示例。

任何用于可视化集群转储输出或 K-mean 输出的工具或方法。

mahout clusterdump \
-d output/vectors/dictionary.file-0 \
-dt sequencefile \
-i output/clusters/clusters-2-final/part-00000 \
-n 20 \
-b 100 \
-o cdump.txt \
-p output/clusters/clusteredPoints/

只需将上面的所有行复制粘贴到文本编辑器中，将您的参数-d, -dt, -i,-p小心地作为我的。

ps 路径来自 HDFS。
