You will probably need to make an interpreter for it, or use an existing one.
https://zeppelin.apache.org/docs/0.7.0-SNAPSHOT/manual/interpreters.html You will find the list of existing interpreters in the menu. If you do need to create one, then you can refer to this guide https://zeppelin.apache.org/docs/0.7.0-SNAPSHOT/development/writingzeppelininterpreter.html On Thu, Sep 8, 2016 at 3:56 PM, kant kodali <kanth...@gmail.com> wrote: > @spacewalkman Just an FYI I don't have anything to do with Spark at the > moment.
