Description

That's a regression introduced with ZEPPELIN-3013.

Using dash or underscoe characters in interpreter name results in the following error when running a note.

E.g. having an interpreter named sparkT-group1 results in error:

Either no interpreter named sparkT or it is not binded to this note
java.lang.RuntimeException: Either no interpreter named sparkT or it is not binded to this note
