    Description

      Right now, example queries are failing with native tables. Seems, query is successfully completed but returning result set as null.

      Query:drop table temp1
      Status:SUCCESSFUL:Query is successful! - Result Available
      Total time in millis:610
      Driver run time in millis:25
      Result:
      Exception in thread "main" java.lang.IllegalStateException: Failed to get resultset, cause:HTTP 500 Can not create a Path from a null string
