> I'm using TableIndexed to manage a secondary key that I use for lookups from Thrift.
I think this is a potentially common use case.
> - Add a UniqueIndexKeyGenerator to use the exact value of the indexed column in the primary
table as the row key in the index table.
> - Add support for creating indexes to the Hbase shell
> I'm attaching the UniqueIndexKeyGenerator patch. I will add a test and also add the changes
to the shell soon.
