Andrew Perepelytsya commented on HIVE-138:
------------------------------------------

Adam, it doesn't look like 'with header' syntax was implemented as described 
originally, but I checked the patch diff and setting this option did work for 
me in 0.7.x:
{code}set hive.cli.print.header=true;{code}
                
> Provide option to export a HEADER

> col1    col2    col3
> 1   9   6
> 7   5   0
> 7   5   3
> SELECT f.col1-f.col2, col3 WITH HEADER FROM some_table foo limit 3;
> f.col1-f.col2     col3
