Hello,

After a system upgrade, we have a Hadoop 2.5.0 cloud instance. We are
trying to run Mahout on top of it. We are using Mahout 0.9 (downloaded from
http://mahout.apache.org/general/downloads.html )

https://issues.apache.org/jira/browse/MAHOUT-1329 indicates Mahout supports
Hadoop 2.2.0

But even with mvn clean install -Dhadoop2.version=2.2.0 -DskipTests=true,
it doesn't appear Hadoop 2.x jar is downloaded anywhere (i.e., there is
only Hadoop 1.2.1 jar downloaded, which is what the pom.xml dictates).

Further, a simple HDFS I/O call would fail (i.e., creating an HDFS file).
It seems Hadoop 2.2.0 is not quite compatible with Mahout 0.9

My question is:
(1) Does Mahout support Hadoop 2.5.0 or should I check out the code from
git (as suggested at
http://mahout.apache.org/developers/buildingmahout.html) in order to get a
Hadoop 2.x friendly Mahout ?

Thanks!

Wei
