Mahout 0.9 on Hadoop 0.20.2

Hi Marko, Nothing special needs to be done to get Mahout 0.9 running on Mahout 0.2. The steps are same as 1.2.1. You might refer to this link http://chandramanitiwary.wordpress.com/2014/03/20/installing-apache-mahout-on-ubuntu/ and there are other good links to for the same. I don't remember the

Hi Chandramani, Thanks, I'll try it. And thanks for your post, it is good. I hope that sanity check will be enough for the cause. Can you please tell me how can I deploy with Hadoop 0.20.2? I have tried my approach locally, that is, I downloaded Mahout, got Hadoop 1.2.1 with it, and

Lucene version compatibility

2014-10-28 Thread Tom LAMPERT
Hello, Does anyone know whether it is possible to upgrade the version of lucene that mahout's lucene.vector and luecene2seq functions are compatible with? Currently they require lucene 4.6.1 indexes but this version is already quite dated... Kind regards, Tom
