Mahout集羣不讀取輸入

Question

嗨，大家好，我正在嘗試爲k-mean Clustering Algo運行集羣轉儲。它不工作。任何想法？這是Mahout在psudo模式集羣中的實例。

任何可視化來自羣集轉儲的輸出或來自K均值的輸出的工具或裝置。

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/ 

只要複製粘貼上面的文本編輯器中的所有行，把你的參數-d，-dt，-i，仔細-p礦山。

p.s路徑來自HDFS。
