Gunther Hagleitner updated HIVE-2693:
-------------------------------------
Attachment: HIVE-2693-12-SortableSerDe.patch
HIVE-2693-12-SortableSerDe.patch adds DECIMAL decimal to the LazySortableSerDe.
It also adds tests for order by asc/desc, group by, distinct and join.
The serialization is similar as described before: <sign><factor><digits>
where:
<sign> = -1,0,1 (zero has it's own sign now)
<factor> = factor is the position of the first digit before the decimal point
(>1) or the first non zero after the decimal point
<digits> = string of digits of the number without the decimal point
> Add DECIMAL data type
