 Review comment:
   In case of the beeline outputs we don't need the header here in the output. So for some
reason the output here doesn't contain it, still it will be there in the actual real BeeLine
output. When it was present here too, the tables had 2 headers, by removing this row they
will only have one. Which is not shown in the test output :) Kind of confusing, we should
have a jira for making the TestBeeLineDriver writing characters to the output files exactly
as a real BeeLine would.

> DESC TABLE operation is having the following bugs:
>  # Whole table descs have two headers.
>  # Table column desc has incorrect long header, while the table is transposed having
the headers in the first column.
>  # Json formatted data also has the headers.
>  # Json formatted data doesn't have the column statistics in it.
>  # There is no TestBeeLineDriver test for desc table, thus the actual output is not tested,
just some intermediary.
