Hi Gokhan,

I've followed the instructions mentioned above and build master branch of https://github.com/apache/mahout
locally and used the dependencies below when running Mahout job but I am still experiencing
error below.

[Dependencies]
mahout-core-1.0-SNAPSHOT.jar
mahout-math-1.0-SNAPSHOT.jar
hadoop-annotations-2.2.0.jar
hadoop-auth-2.2.0.jar
hadoop-common-2.2.0.jar
hadoop-mapreduce-client-common-2.2.0.jar
hadoop-mapreduce-client-core-2.2.0.jar
hadoop-yarn-api-2.2.0.jar
hadoop-yarn-client-2.2.0.jar
hadoop-yarn-common-2.2.0.jar
hadoop-yarn-server-common-2.2.0.jar
commons-cli-2.0-mahout.jar

[Error]
14/06/02 13:50:30 INFO Configuration.deprecation: mapred.output.dir is deprecated. Instead,
use mapreduce.output.fileoutputformat.outputdir
Exception in thread "main" java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext,
but class was expected
at org.apache.mahout.common.HadoopUtil.getCustomJobName(HadoopUtil.java:166)
at org.apache.mahout.common.AbstractJob.prepareJob(AbstractJob.java:579)
at com.bestbuy.recs.mahout.algorithms.BinaryStep.run(BinaryStep.java:82)

Wanted to ask help if I have missed something out.

Regards,
