---------------------------------------

Edward,

> But, i don't know the movements opposed to shell operations.

I don't think there is opposition to what you are doing, other than some people 
feel that the advanced shell operations are not necessary in a basic shell that 
can do simple queries and administrative functions. If the advanced features 
could be packaged in a separate jar and loaded via some command line option, I 
think it would gain higher acceptance.

> I think there can be no cause for complaint.
> The shell tool isn't threatening a pure Hbase.

I think I am misunderstanding something here. Are you proposing to do the data 
types entirely outside of HBase or leveraging HADOOP-2197 ? Or do you want 
internal support for data types?

If you are thinking of the former, that's fine. But I don't think support for 
data types should be in the core of HBase.

> 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)
