Writing a custom interpreter: how to use an external repository + class loading problem

[Manuel Vonthron <mv...@mnubo.com>]

Hi guys,

I'm starting to play with Zeppelin and I find it awesome, this is such a
great project, thanks a lot to all the contributors.

Now I have two issues at this point I'd like your help with:

*1. Can we use a private repository in addition to Maven central and the
local filesystem to publish a custom interpreter?*
I would like to write a custom interpreter and while I'm working on it, I
am deploying to a private Maven repository (a JFrog Artifactory instance).

I have been able to fetch my interpreter by overriding the
ZEPPELIN_INTERPRETER_DEP_MVNREPO env var (oddly enough, it didn't work by
modifying the zeppelin-site.xml) but I loose access to Maven central for
the rest of the interpreters and libraries.
Ideally I would have configured an arbitrary set of repositories in the
interpreterRepositories section of the interpreter.json file.

Does this make sense? Is there a way to do something like this?

2. Even after installing my custom interpreter and setting what I hope are
the right settings in interpreter.json, when I try to actually use it, I
end up with a "ClassNotFoundException" (https://pastebin.com/raw/9TbE7g6u),
although the class is indeed it the right folder under interpreter/ in the
right jar.
It's a bit hard to describe what I've done and what I haven't but do you
have any idea what I could have missed? Is there some kind of a "usual"
mistake I could have run into?


Thanks for your help
Manuel
