Description

This unit test is printing 10.000 rows all equal to the following line:

field2(VARCHAR:REQUIRED)[$offsets$(UINT4:REQUIRED)]

DrillTestWrapper contains the following code in 2 separate methods that prints a field's details whenever an "empty" value is encountered:

            if (obj instanceof Text) {
              obj = obj.toString();
              if (obj.equals("")) {
                System.out.println(w.getField());
              }
            }

Because this particular unit test was creating 10K rows with an empty field, it was causing lot's of output to Stdout.
