In the meantime, you might apply the patch in MAHOUT-1354, build mahout
using mvn package -Phadoop2 -DskipTests=true, use that mahout version and
see if that works

Well, I can say there is a work in progress for building mahout against
hadoop2.

Per this link, one notability incompatibility is Counter and CounterGroup.

Could you check the following?
Are you sure that your hadoop cluster is hadoop 2.2.0?
Are you sure other dependencies of your project do not have a transitive
dependency to hadoop?

Hi Zoltan,
I am saying that hadoop2-stable and hadoop1 are binary compatible. I don't know
what version of hadoop is used in cdh4-mr2 but I guess it was hadoop2 alpha,
since bigtop was at hadoop 2.0.6 alpha last time I checked, which was last week.
Just try it and let us know if you experience
Sebastian,
R we still using SplitInputJob, seems like its been replaced by a much newer
SplitInput.
Do u think this needs to be purged from the codebase for 0.9, its been marked
as deprecated anyways?

I think there are still parts of the code (e.g. in DistributedRowMatrix)
that use the old API.

Mahout is using the newer mapreduce API and not the older mapred API.
Was that what u were looking for?

Hi Gokhan,
Thank you for the clarification.
Does it mean that Mahout is using the mapred API everywhere and there is
no mapreduce API left? As far as I know, the mapreduce API needs to be
recompiled and I remember needing to recompile Mahout for CDH4 when it
first came out.
Thanks, Zoltan
I meant that you shouldn't need to modify mahout's dependencies, just mvn
package and it should work against hadoop 2.2.0 (Yeah, 2.2.0 is not alpha)
Quoting from
http://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/MapReduce_Compatibility_Hadoop1_Hadoop2.htm
Hi Gokhan,
My project currently fetches every dependency through Maven--is there any way I
can grab the version you mentioned that way?
In that vein, I am using the following version of hadoop:
org.apache.hadoop
hadoop-client
2.2.0
That's not alpha, right?
Thanks!
Mahout actually should work with hadoop-2 stable without recompiling,
not with hadoop-2 alpha though.
We're, by the way, currently in the process of adding support to build
mahout with hadoop-2.
Please see mahout-1354 for the relevant issue

Is Dec 2013 still the intended release date of the next mahout release that
will be compatible with Hadoop 2.2.0?
