Thanks Lance, i'll try rolling back a few versions to see if i can get an output.
The output directory from the classifier holds the following: -rwxrwxrwx 1 root root 84K Jul 26 20:11 part-m-00000 -rw-r--r-- 1 root root 676 Jul 26 20:11 .part-m-00000.crc -rwxrwxrwx 1 root root 0 Jul 26 20:11 _SUCCESS -rw-r--r-- 1 root root 8 Jul 26 20:11 ._SUCCESS.crc Cheers Sam > Date: Mon, 30 Jul 2012 14:28:37 -0700 > Subject: Re: FW: cmdump > From: [email protected] > To: [email protected] > > I don't know what the output directory holds. > > There used to be code in TestNaiveBayesClassifier that saved the > confusion matrix to a separate file.
