Thank for your replies! Mahout 0.12.0 from command line worked great.
However, if I want to develop the same example with Java API, what version of mahout-core should I use in the pom.xml? I tried mahout-core 0.12.0, but it does not exist. With mahout-core 0.9 I got the same exception as in the previous email. java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext, but class was expected The exception was thrown during training of Naive Bayes model. I use TrainNaiveBayesJob and ToolRunner classes to train the model. 2016-04-25 16:06 GMT+03:00 Alen Xia <summer...@yahoo.com.invalid>: > https://issues.apache.org/jira/browse/MAHOUT-1354 > > Hope that helps :) > > 发自我的 iPhone > > > 在 2016年4月25日，18:27，Nantia Makrynioti <nantiam...@gmail.com> 写道： > > > > Hello, > > > > I have installed Hadoop 2.2.0 on an Ubuntu 14.04 machine.
