Github user jongyoul commented on the issue: https://github.com/apache/zeppelin/pull/1145 @Leemoonsoo I agree that this PR lower user experience in your case. It's better to support that feature for backward compatibility. BTW, I also think this makes users confused because user has no interpreter setting like `spark` but can run with `%spark`. I'll handle this issue with [ZEPPELIN-1191](https://issues.apache.org/jira/browse/ZEPPELIN-1191) because it's out of scope of this issue. I merge it now and go for the next issue.
