[jira] Commented: (MAHOUT-167) Convert clustering code to Hadoop
0.20 API
[ https://issues.apache.org/jira/browse/MAHOUT-167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12748917#action_12748917 ]
Sean Owen commented on MAHOUT-167:
----------------------------------
So, I updated to 0.20.0 a while back, and have wrestled with it periodically since then. It doesn't work. The new Hadoop APIs are there, yes, but the framework assumes you are not using them. You'll get all sorts of doesn't-implement-the-old-interfaces errors if you try. And it doesn't like like this is changed in HEAD. I would not bother updating until the new APIs work
Or else, I am completely missing something.

Thanks for the heads-up. I saw that you have updated to the new APIs but
I assumed they worked as advertised. There are a lot of changes required
to update the clustering so I will proceed as far as I can get and then
just attach a WIP patch to the issue. I will probably just do Canopy to
see how it works.
