We already allow setting default interpreter when creating note. Another way to set default interpreter is to reorder the interpreter setting binding in note page.
But personally I don't recommend user to use short interpreter name because of default interpreter. 2 Reaons: 1. It introduce in-accurate info. e.g. In our product, we have 2 spark interpreters (`spark`: for spark 1.x & `spark2` for spark 2.x). Then user often specify `%spark` for spark interpreter. But it could mean both `%spark.spark` and `%spark2.spark`, So usually it is very hard to tell what's wrong when user expect to work spark2 but actually he still use spark 1.x. So usually we would recommend user to specify the full qualified interpreter name. Just type several more characters which just cost 2 seconds but make it more clear and readable. 2. Another issue is that interpreter binding is stored in interpreter.json, that means if they export this note to another zeppelin instance, the default interpreter won't work. So I don't think setting default interpreter via interpreter binding is valuable for users. If user really want to do that, I would suggest to store it in note.json instead of interpreter.json Jongyoul Lee <jongy...@gmail.com>于2018年7月6日周五 下午3:36写道： > There are two purposes of interpreter binding.
