I don't think so.
What do you think about this ment.
- The shell should really only be a administrative utility anyway, just enough
to be *reboot* and *dir* and to peek at a *file name* here or there.
>> It would add a ton of overhead to everything in HBase and require a huge
>> overhaul of how stuff works.
>> It would also take away a good deal of flexibility.
I don't think so. you can just use the byte[]. ok?
Also, applications developers need to modeling capacity on Hbase. (It's very
difficult in my experience, so shell's guide will be very useful.)
>> I doubt that people who write their applications to use HBase are going to
>> be limited by the lack of built-in data types.
I don't think so.
If you are studied Database and Math, you can really powerful use the Some DB
solutions.
But, many peoples(application developers) can't.....
Why...?
More think please.

> 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)
