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.

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
