Description
Livy interpreter is not starting a session when I directly call "%livy.sql" magic. Everytime I have to start a session using scala magic and then I need to run sql using sql magic.
It would be better, if livy.sql magic automatically starts a session for me, even if there is no active livy session.
Steps to reproduce the issue:
1. Restart the livy interpreter.
2. Run a sql as follows
%livy.sql show tables
In the log we can see an error message as below.
