[jira] [Created] (ZEPPELIN-154) Load Interpreter via Classpath

Eric Charles created ZEPPELIN-154:
-------------------------------------

             Summary: Load Interpreter via Classpath
                 Key: ZEPPELIN-154
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-154
             Project: Zeppelin
          Issue Type: New Feature
          Components: Interpreters
    Affects Versions: 0.5.0
            Reporter: Eric Charles


For now, the classloader is built with a URLClassloader which loads jar fils from the local file system based on the interpreter name.

It restricts the list of classloaders to the defined interpreters names.

This does not allow to use interpreters jars embedded in the current server class loader, restricting the development of external interpreter ecosystem.

We should have an option to allow external interpreters to be used. When this option would be activated, the resitriction to the list folders would be removed.

I will propose a pull request which implements such an option. The init() method of InterpreterFactory class will be impacted.
