[jira] Commented: (MAHOUT-167) Convert code to Hadoop 0.20 API

["Drew Farris (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12887624#action_12887624 ] 

Drew Farris commented on MAHOUT-167:
------------------------------------

In WikipediaDatasetCreatorDriver in r962391 line 194, the wikipedia.categories property is added to the configuration after the job is created. Since the config is cloned at job creation time this property never makes it to the job members and thus breaks the code. 

Not sure if this anti-pattern is repeated elsewhere in the hadoop-0.20 migration code, but it might be worth further investigation.
