使用 Mahout seq2sparse 命令，我成功地在 HDFS 中创建了以下文件夹
df-count
dictionary.file-0
frequency.file-0
tf-vectors
tfidf-vectors
tokenized-documents
wordcount
之后，当我使用以下语法运行 trainnb 命令时
mahout trainnb -i tweet-vectors -el -li labelindex -o model -ow -c
我收到以下错误。有谁知道同样的分辨率？
Exception in thread "main" java.lang.IllegalStateException: hdfs://machineinfo:8020/user/hhhh/tweetvectors/df-count
