Edward Yoon commented on HADOOP-2329:
-------------------------------------
Let's see the integer value example.
{code}
int integer = 123456789;
ByteBuffer buff = ByteBuffer.allocate(Integer.SIZE / 8);
buff.putInt(integer);
buff.order(ByteOrder.BIG_ENDIAN);
1: table.put(lockId, column, buff.array());
2: table.put(lockId, column, "123456789".getBytes());
{code}
4 bytes vs 9 bytes.
Nine is the almost double of four.

>
> A built-in data type is a fundamental data type that the hbase shell defines.
> (character strings, scalars, ranges, arrays, ... , etc)
> If you need a specialized data type that is not currently provided as a
> built-in type,
> you are encouraged to write your own user-defined data type using UDC(not yet
> implemented).
> (or contribute it for distribution in a future release of hbase shell)
