@viirya So it seemed odd to have the generated output files to have column
names sorted which didn't reflect the columns. In the test case i had the table
create like following.
```SQL
CREATE TABLE showcolumn2 (price int, qty int) partitioned by (year int,
month int)
```
It seemed odd to me to have the generated output file report the columns as
month, price, qty and year as opposed to price, qty, year and month.
