​Thanks for the efforts on the classpath. However, as stated above, the classpath required to execute Zeppelin and the classpaths required of the individual interpreters have already diverged. Since it is the interpreters that will have the most dynamic development, I should actually suggest separating the build and runtime classpaths of the interpreters from the Zeppelin build/runtime.
Interpreter API changes will be more difficult, but in the long run I believe it will make for a much more diverse set of interpreters available. paul On Wed, May 13, 2015 at 3:42 AM, RPCMoritz <g...@git.apache.org> wrote: > Github user RPCMoritz commented on the pull request: > > > https://github.com/apache/incubator-zeppelin/pull/65#issuecomment-101553576 > > While this was a decent effort (it actually made my classpath-related > error almost readable, where previously it was three screens worth of > text), there is still an issue with classpath's lack of simplicity.
