[jira] [Commented] (MAHOUT-969) testclassifier should check if the model file actually exists

    [ https://issues.apache.org/jira/browse/MAHOUT-969?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13635170#comment-13635170 ] 

Suneel Marthi commented on MAHOUT-969:
--------------------------------------

Is this issue still valid given the present baseline?  'testclassifier' has been long retired and replaced by classify-20newsgroups.

> The ./mahout testclassifier command for naive bayes does not check if the -model argument actually exists on the hdfs file system.
> If it does not exist, it appears to run successfully, but generates all zeroes in the results.
