> When debugging timeline POCs, we may need to create hbase tables that are
> added in some ongoing patches. Right now, our schema creator will exit when
> it hits one existing table. While this is a correct behavior with end users,
> this introduces much trouble in debugging POCs: every time we have to disable
> all existing tables, drop them, run the schema creator to generate all
> tables, and regenerate all test data.
> Maybe we'd like to add an "incremental" mode so that the creator will only
> create non-existing tables? This is pretty handy in deploying our POCs. Of
> course, consistency has to be kept in mind across tables.
