Can you share the exact command you are running?   The link you supplied goes through a redirector we can't access, and the important part got cut off. Maybe you can clarify what page you are looking at under the installation guide. ... View more

The proximate problem is that some host name is configured as "user", which doesn't sound like a host name. I would first look through all the host-related settings in your Hadoop conf to see where "user" appears and identify if any of these should be something else. ... View more

I think you have found the right file then, but it is saying that it did not generate cluster centers. Maybe the data is too small. This might be better as a question on the Mahout mailing list as to what that means. ... View more

Yeah that's why I'm confused here. Is it not hte part-r-00000 that likely has the data? The format is a binary serialization and you can't open it as if it is a text file. ... View more

Do the files have data in them? I would double-check that they are not 0-length, but I doubt it. What directory do you find the files in? I suspect its name is like "part-m-00000" but your code appears to be listing "part-m-0" ... View more

If I'm not mistaken, you have built your own application that embeds code from Mahout 0.8. That is not compatible with Hadoop 2, and CDH5 is based on Hadoop 2.3+. It also includes a distribution of Mahout 0.8 that has been modified to work on Hadoop 2.    To make this work, you can try to depend on the 0.8 distribution of Mahout from CDH 5 in your project instead, since it contains necessary modifications.    For example, if building with Maven, instead of specifying version 0.8 for artifact org.apache.mahout:mahout-core you would specify 0.8-cdh5.0.0 . You would also need to reference the Cloudera repo in your build.   You could also recompile Mahout locally for Hadoop 2, but I think this is the most trouble. ... View more
