Subject Re: Internalscanner problem in HBase

As you may have concluded from reading the code (since you found
InternalScanner), the classes that implement the interface are scoped
on the region to which they belong and not the table. Only the client
has a full view of a table, and it's what you should be using.

Hope this helps,
