I wrote a message to the hadoop list about it. Also i found this
https://issues.apache.org/jira/browse/MAHOUT-1498 ticket.
Could it be a related bug?

That sounds like a Hadoop list question.
All I can say is there is a job.jar in mrlegacy/target with all dependencies
packaged. This should have everything needed for lda.

Hello again,
maybe my question was misleading.
I am asking whether the intended usage is to provide the job with the required
library’s and sent those together with the job to yarn(if yes how can this be
done?), or to add the required classes to the classpath of every node in the
cluster.
What is the best practice?

Hello,
the first error was due to a missing property in yarn.xml. However no i have a
different problem.
i am working on a web application that should execute lda on a external yarn
cluster.
I am uploading all the relevant sequence files onto the yarn cluter.
This is how it try to remotely execute lda on the cluster.

So apparently the job misses some mahout classes. How can i provide the
required classes to yarn?
