@jeffsteinmetz A couple of things are happening here --
First, I would expect it to fail if you run it from zeppelin-distribution
because the pom's aren't setup to include it in the distribution binary. That
is on the list of "to-do's," and is planned for after the initial merge.
Second, every time I've seen that error, it was because Zeppelin was
configured to try to launch spark from Zeppelin home rather than from a
SPARK_HOME. It looks to me that that's what was happening here when you try to
run it from the distribution directory. (Is SPARK_HOME set?) *But* the R
interpreter should be detecting whether there's a misconfiguration and, if so,
failing gracefully. The reason it isn't may be because of the pom/distribution
issue. Can you email me the spark interpretergroup log of that run?
Before anyone asks -- requiring SPARK_HOME is a feature, not a bug.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastruct...@apache.org or file a JIRA ticket
with INFRA.
