Yes, it's good functionality. Just making sure you understand all the
pieces you'll need.
I would expect you to add a renameTable method to HBaseAdmin and
create a RenameTable subclass of TableOperation in the master.

+1 Bryan. In the future, we need to be able to recover HBase
entirely from the file system
without either the META or ROOT region's help since they may be
corrupted.

Subject: Re: Renaming the table.
I'm not sure I understand. Do you mean you'd maintain a
mapping between the old, actual table name and the new,
logical table name? I don't really like that idea. It sounds
like it would add a ton of failure cases and complexity to
the system. We need tables to stay in a really consistent
state so that we can have as much data reliability as possible.

In fact, i thought a physical/logical table name management for
high-performance without no changing the meta data.

The SQL way to do this would be "ALTER TABLE table RENAME
new name".
However, that's a bit verbose, so I think "RENAME table TO
new_table"
would be fine.

A renaming function of table alteration is needed.
Is there a tool for renaming the table?
Any ideas please post back.
Also, i'd like to add renaming syntax to hql as describe below.
hql > RENAMING table_name TO new_table_name;
What do you think?
