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

Naveen Gangam created HIVE-7200:
-----------------------------------

             Summary: Beeline output displays column heading even if --showHeader=false is
set
                 Key: HIVE-7200
                 URL: https://issues.apache.org/jira/browse/HIVE-7200
             Project: Hive
          Issue Type: Bug
          Components: CLI
    Affects Versions: 0.13.0
            Reporter: Naveen Gangam
            Priority: Minor


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.
