@sundarshankar89 I might need your help to debug the failing integration tests

[sundarshankar89]

@ericvergnaud Can you split this PR with code changes and then separate PR to remove the test examples SQL.
That way it is easier to Review.

We had this conversation when this was all originally under unit and moved over to integration. few tests are unit and few really depend on spark infra.
