[jira] [Commented] (MAHOUT-1527) Fix wikipedia classifier example

["Andrew Palumbo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-1527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13994074#comment-13994074 ] 

Andrew Palumbo commented on MAHOUT-1527:
----------------------------------------

The issue re: crashing testnb should probably be addressed in the future- either by rejecting unrecognized labels or by changing TrainNaiveBayesJob's - l option  (which doesn't seem to work right now- though i didnt spend too much time looking at it.)

> The examples package has a classification showcase for prediciting the labels of wikipedia  pages. Unfortunately, the example is totally broken:
> It relies on the old NB implementation which has been removed, suggests to use the whole wikipedia as input, which will not work well on a single machine and the documentation uses commands that have long been removed from bin/mahout. 
> The example needs to be updated to use the current naive bayes implementation and documentation on the website needs to be written.
