I understand you just want to experiment, but I think it will be unlikely we will switch to 0.21 given what has been reported about this release. Given this situation, is it possible to stick with the current implementation until the later releases improve?
-----Original Message----- From: Shannon Quinn [mailto:[email protected]] On Behalf Of Shannon Quinn Sent: Wednesday, November 17, 2010 3:54 AM To: [email protected] Subject: Re: [jira] Commented: (MAHOUT-537) Bring DistributedRowMatrix into compliance with Hadoop 0.20.2 I wanted to keep the old code as a quick-and-dirty reference, but I will delete on the next patch. Not sure when that will be, as we are nearing the end of the semester... The unit tests that are failing should be the ones that depend on DRM.times(), as well as any that invoke its constructor (which has changed). Those should be fixed once I finish the conversion of times(). However, I still haven't figured out how to use a different version of Hadoop in my build; Maven pulls version 0.20 in by default and I can't seem to find where to modify this, and even if I could I don't know what I'd modify it to. I understand there's a whole other discussion about whether or not a different version of Hadoop is the answer, but I want to see if this works at all first. If not, I have another (but slightly more hacky) approach I could use. Anyone know how to do this?
