Above comment means... "I didn't said that Hbase should provides built-in data
type."
Let's see the example.
Some DB solutions can be provide only byte[] data type.
And then, ... listen to their slogan.. "you can stores own arbitrary data type.
look!! this is awesome flexible DB solution. Let's make your own datum and data
types. ".....
We can think about why they didn't...
Also, i think it is not makes any problem.
It just makes user can choice, so we can provides convenience.
only byte[] VS { integer or character or byte[] or .... , etc}
It means that each user needn't develop the exist built-in data type in
everytime.

> Key: HADOOP-2329
> URL: https://issues.apache.org/jira/browse/HADOOP-2329
> Project: Hadoop
> Issue Type: New Feature
> Components: contrib/hbase
> Affects Versions: 0.16.0
> Reporter: Edward Yoon
> Assignee: Edward Yoon
> Fix For: 0.16.0
>
>
> 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)
