Another annoying Mahout Error on running the Mahout jobs.
Well this is caused because of the reason already discussed. The mahout is not build explicitly for Hadoop 2.
So all it needs is a small re build of Mahout:
mvn clean install -Dhadoop2 -Dhadoop2.version=2.2.0 -DskipTests=true
Thats it. Now mahout slould work just fine.
Drop a note in case you get stuck anywhere.
