None of the Python notebooks are working after this exception has occurred.
The same error can be reproduced in the standard Zeppelin 0.8.1 installation and in the Zeppelin 0.8.1 installation with Docker.
The grpcio Python package is causing the trouble.
When installing the iPython dependencies (including grpcio) on Zeppelin 0.8.0, the same issue is introduced.
We really need this functionality. Can you please try to fix this issue. Thanks.
We have done some testing with different versions of the grpicio Python package but none of them are working.
