Yep, it applies. Any time you launch from the command line. The scalatests
won't catch this case but since you haven't messed with the pom or added any
external deps your 99% sure to be ok.
Probably too soon to try it for the nb stuff. There are a few other tweaks
but wanted comments asap.
> Class dependencies for the spark module are put in a job.jar, which is very

> Project: Mahout
> Issue Type: Bug
> Components: spark
> Affects Versions: 1.0-snapshot
> Reporter: Pat Ferrel
> Assignee: Ted Dunning
> Fix For: 1.0-snapshot
>
>
> using a maven plugin and an assembly job.xml a job.jar is created with all
> dependencies including transitive ones. This job.jar is in
> mahout/spark/target and is included in the classpath when a Spark job is run.
> This allows dependency classes to be found at runtime but the job.jar include
> a great deal of things not needed that are duplicates of classes found in the
> main mrlegacy job.jar. If the job.jar is removed, drivers will not find
> needed classes. A better way needs to be implemented for including class
> dependencies.
> I'm not sure what that better way is so am leaving the assembly alone for
> now. Whoever picks up this Jira will have to remove it after deciding on a
> better method.
