> The current catalog does not support backup and restore feature. Catalog dump feature will print out all tables and others included in catalog as Tajo DDL statements (i.e., SQL) via stdout. It can also be stored as a file via shell redirection.
> Also, we need a script to call catalog dump feature in a convenient way as follows:
> {code}
> $ bin/tajo_dump [table name or db name] > tajo_backup.sql
> {code}
