   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:
        at java.sql.DriverManager.getConnection(DriverManager.java:689) 
~[?:1.8.0_181]

 ~[hive-exec-4.0.0-SNAPSHOT.jar:4.0.0-SNAPSHOT]```
    
   Is there are configuration or workaround for the driver-connection. If you 
have any idea, Let me know
