I am trying to run the 20newsgroups example as mentioned in this page. When I generate input data set using this piece of code

$> $MAHOUT_HOME/bin/mahout org.apache.mahout.classifier.bayes.PrepareTwentyNewsgroups \
-p examples/bin/work/20news-bydate/20news-bydate-train \
-o examples/bin/work/20news-bydate/bayes-train-input \
-a org.apache.mahout.vectorizer.DefaultAnalyzer \
-c UTF-8

all I could get is a warning that states that

No org.apache.mahout.classifier.bayes.PrepareTwentyNewsgroups.props found on classpath, will use command-line arguments only

Is it a bug in mahout itself? How do I fix it?

    I was able to do it. Actually the directory examples/bin/work/20news-bydate/bayes-train-input has been created, but my file explorer didn’t show it instantly even though I refreshed. Later when I did an ls from the terminal, I was able to see the folders created!
