Github user jongyoul commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/835#issuecomment-211214509 @Leemoonsoo Thanks for explaining what the problem is. But `interpreter-setting.json` doesn't include all of interpreters' settings. In case of Spark, `interpreter-setting.json` includes settings of `spark` group. I thought all interpreter with same group - or same jar - deploy at the same time with same jar. For more detail, if I adopt a new mechanism with JDBCInterpreter, I also write a new `interpreter-setting.json` inside a JDBCInterpreter jar or under {interpreter}/jdbc/. Does it makes sense? And about Helium, I've reviewed that codes, and get to know that it has a different structure and doesn't break current one, thus this PR doesn't conflict on registering interpreter. And I'm also willing to move forward to merge a new mechanism in Helium structure after Helium is merged.
