Description
The rpad function - rpad(str1, length [, str2]) returns different result compared to postgres, oracle and mysql when length is less than the lenght of str1. For example:
select * from voter where voter_id=10;
voter_id | name | age | registration | contributions | voterzone | create_time
-----------------------------------------------------------------------------
10 | tom underhill | 75 | socialist | 525.33 | 18592 | 2015-01-24 07:27:05
0: jdbc:drill:schema=dfs> select rpad(name, 8, 'A') from voter where voter_id=10;
------------

The above result from drill truncates the name from right to left. For the other rdbms:
SQL> select rpad(name, 8, 'A') from voter where voter_id=10;
RPAD(NAM
--------
tom unde
Looks like truncation occurs from left to right eventhough it's rpad.
