Subject [jira] [Commented] (HIVE-7200) Beeline output displays column heading even if --showHeader=false is set

Xuefu Zhang commented on HIVE-7200:
-----------------------------------

[~ngangam] Could you repost the new formatting with your patch? The above result seems having
empty lines, which isn't good. Also, add necessary tag so that JIRA will show exactly as you
see in the console.

> A few minor/cosmetic issues with the beeline CLI.
> 1) Tool prints the column headers despite setting the --showHeader to false. This property
only seems to affect the subsequent header information that gets printed based on the value
of property "headerInterval" (default value is 100).
> 2) When "showHeader" is true & "headerInterval > 0", the header after the first
interval gets printed after <headerInterval - 1> rows. The code seems to count the initial
header as a row, if you will.
> 3) The table footer(the line that closes the table) does not get printed if the "showHeader"
is false. I think the table should get closed irrespective of whether it prints the header
or not.
