Description

 When I try to execute any code (Ex: "5+5") in the Apache Toree Kernel inside jupyter lab, no output is visible in the notebook and the jupyter lab log contains the following message:

Note the following additional points:

• spark-shell works fine;

• Apache Toree in the notebook works fine.
