Thejas M Nair commented on HIVE-4545:
-------------------------------------
[~appodictic] Without this patch, 'describe table' in beeline running against
hive server2 returns something like
{code}
'a ','int ','None '
{code}
instead of
{code}
'a','int',''
{code}
While it might make sense for the hive cli to add space padding and replace
empty comments with None, that is not a good idea for jdbc application. For
example a jdbc based gui tool will take of formatting on its side.
The goal is to be able to get 'raw' data from the familiar DDL commands without
any changes to make it more human readable.
> HS2 should return describe table results without space padding

> HIVE-3140 changed behavior of 'DESCRIBE table;' to be like 'DESCRIBE
> FORMATTED table;'. HIVE-3140 introduced changes to not print header in
> 'DESCRIBE table;'. But jdbc/odbc calls still get fields padded with space for
> the 'DESCRIBE table;' query.
> As the jdbc/odbc results are not for direct human consumption the space
> padding should not be done for hive server2.
