How should I solve the problem? Thank you! Dear Grant,

I got an exception when trying mahout 0.3 locally at step 2 in LDA test:

CMD is:
./mahout org.apache.mahout.clustering.lda.LDAPrintTopics –input /content/reuters/seqfiles-TF/lda-output/state-19 –dict /content/reuters/seqfiles-TF/dictionary.file-0 –words 10 –output /content/reuters/seqfiles-TF/lda-output/topics –dictionaryType sequencefile

And the warning & exception is:

WARNING: No org.apache.mahout.clustering.lda.LDAPrintTopics.props found on classpath, will use command-line arguments only
May 20, 2010 10:13:27 PM org.slf4j.impl.JCLLoggerAdapter error
