             Summary: Interpreter does not bind after remove & add interpreter
                 Key: ZEPPELIN-229
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-229
             Project: Zeppelin
          Issue Type: Bug
            Reporter: Eran W


After removing an interpreter and adding it back notebooks which were bounded to the removed interpreter does not re-bind to the new interpreter.

Repro steps:
open a notebook and try %md ### this is a test
2) Run it and get the expected results
3) remove the interpreter using the interpreter settings page
4) try running the paragraph again and get an error : "md interpreter not found"
Log file will show:

5) Add the interpreter back using the interpreter setting page
6) try running the paragraph again
still getting the same error both on page and in log
7) open a new notebook and try using md
8) everything works fine in the new notebook
