The assertion error is due to the fact both shaded and non shaded jars are
there in classpath.

Post ``at java.sql.DriverManager.getConnection(DriverManager.java:664)
~[?:1.8.0_181]`` rather than coming back to ``hive-exec`` it goes back to the
non shaded jars ``calcite-core``
The driver gets registered with original jar only so it executes call to the
non-shaded ones.
Ideally we can remove the original ones for itests??
Removing that takes away that error, but driver registration is done as
``HiveDriver`` and while getting connection it wants a `jdbc:calcite`
hard-coded in `Framework` class so it gets a:
```
Caused by: java.sql.SQLException: No suitable driver found for jdbc:calcite:

```
Is there are configuration or workaround for the driver-connection. If you
have any idea, Let me know
