Question

大家好我正在尝试为k-mean Clustering Algo运行群集转储。它没有工作。任何的想法？这是关于psudo模式集群的Mahout in Action的示例。

可视化集群转储输出或K-mean输出的任何工具或方法。

Answer 1

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/

只需在文本编辑器中复制粘贴上面的所有行，将-d，-dt，-i，-p的参数小心地作为我的参数。

p.s路径来自HDFS。

Mahout聚类不读取输入
