Description

The current lpad and rpad don't support the multibyte character at "str" and "pad".
For example, we can see the following result.

hive> select name from sample1;
OK
tokyo
ＴＯＫＹＯ
hive> select lpad(name, 20, '*') from sample1;
OK
***************tokyo
*****ＴＯＫＹＯ

This is improved as follows.

hive> select lpad(name, 20, '*') from sample1;
***************tokyo
***************ＴＯＫＹＯ
