测试mahout in action 中kmean实例的时候,输入命令:
bin/mahout kmeans -i reuters-vectors/tfidf-vectors/ \
-c reuters-initial-clusters \
-o reuters-kmeans-clusters \
-dm org.apache.mahout.common.distance.SquaredEuclideanDistanceMeasure \
-cd 1.0 -k 20 -x 20 -cl
报出先面的错误

解决办法:输入命令参数o 前面没有加- ,mahout不能解析后面的参数,所以报出来的错误.
