---------------------------------------

+1 to this.

this is very useful and it is quite simple to add to the CliDriver code.

> The result row(s) on CLI are displayed without column header.
> It would be useful to be able to set header on or off by users.
> for example,
> hive> SET HEAD [ON|OFF]    /* similar to oracle sql*plus syntax */
> or
> hive> SET [GLOBAL|SESSION] HEADER=[ON|OFF]    /* similar to mysql's "SET" syntax */
