thank you Pat. I was having that issue when I was trying to do something like
that.
Just curious, how should I prepare the data so that it can satisfy drmDfsRead
(path) ? DRM format and how to create the DRM file ? thanks, canal

Thank you very much for the help. I will try Spark 1.4.
I would like to try distributed matrix multiplication. not sure if there are
sample codes available. I am very new to this stack. thanks, canal

Mahout 0.11.0 is built on Spark 1.4 and so 1.5.1 is a bit unknown. I think the
Mahout Shell does not run on 1.5.1.
That may not be the error below, which is caused when Mahout tries to create a
set of jars to use in the Spark executors. The code runs `mahout -spark
classpath` to get these. So something is missing in your env in Eclipse. Does
`mahout -spark classpath` run in a shell, if so check to see if you env matches
in Eclipse.
Also what are you trying to do? I have some example Spark Context creation code
if you are using Mahout as a Library.

Hello,I am running a very simple Mahout application in Eclipse, but got this
error:
Exception in thread "main" java.lang.IllegalArgumentException: Unable to read
output from "mahout -spark classpath". Is SPARK_HOME defined?
I have SPARK_HOME defined in Eclipse as an environment variable with value of
/usr/local/spark-1.5.1.
What else I need to include/set ?
thanks, canal
