----------------------------------
Hi [~seungunchoe].
At TAJO-721, we are trying to support nested structure types.
To support nested structure types, it is inevitable to change the catalog
database schema.
Honestly, the catalog database can be changed if it is required.
You should move the meta information from the old catalog to the new one.
Please refer to
http://tajo.apache.org/docs/current/backup_and_restore/catalog.html.
> Old version catalog databases dose not work on tajo-0.11.0-SNAPSHOT.

> Priority: Minor

> In my case, make catalog database set on tajo-0.9.0-SNAPSHOT.
> This catalog worked on tajo-0.9.1-SNAPSHOT and tajo-0.10.0-SNAPSHOT.
> But, it does not work on tajo-0.11.0-SNAPSHOT.
> So, I change META table's value at catalog database. ( 2 -> 3 )
> But, it does not working.
> I think old version catalog database can use any time, any version tajo.
> (My catalog databases is on mysql.)
