我通过设置运行 mahout kmeansMAHOUT_LOCAL="True"

以下是我的 shell 脚本中的命令。

mahout kmeans --input ./seq_input/ --output ./output --numClusters 4 --maxIter 10 --convergenceDelta .0001 --clustering --distanceMeasure org.apache.mahout.common.distance.CosineDistanceMeasure --overwrite --clusters ./centroid_vectors

在运行脚本时，我遇到了错误

Unknown program 'kmeans' chosen.

以下是日志信息：

MAHOUT_LOCAL is set, so we don't add HADOOP_CONF_DIR to classpath.

是什么导致了这个错误？
