I love helpful error messages ;-) Can you check the classpath to see if there
any additional classes that are there? I’ve gotten connection issues like this
when I had a database driver in the CLASSPATH.
Also take a look at this response:
Thank you. This gives us a wonderful exception:

The issue is not in joining, Drill can join empty schemaless table (for
example empty JSON file or empty directory).
DRILL-4517 is exactly describes the issue. You can add your test case with
