Mahout needs to be made compatible with Hadoop .22 and Hadoop .22 releases
--------------------------------------------------------------------------
Key: MAHOUT-822
URL: https://issues.apache.org/jira/browse/MAHOUT-822
Project: Mahout
Issue Type: Improvement
Components: build
Reporter: Roman Shaposhnik
Attachments: MAHOUT-822-build.patch.txt
As part of the Hadoop stack integration project (Apache Bigtop) we are now
trying to compile Mahout's upcoming 0.6 release against Hadoop 0.22 and 0.23.
I'm attaching the patch to Mahout's Maven build system that made it possible. I
would also like to request help in solving the real issues that poped
up when we tried to compile Mahout:
