Bill Bejeck commented on SPARK-3299:
------------------------------------
This change is a little more involved as it requires modifying the Catalog
trait.
My current plan is to add an abstract method to the Catalog trait and have any
objects extending Catalog override a 'listTables' method.
The SQLContext object uses an instance of SimpleCatalog for any table
operations. Any additional public method defined to list the tables will
delegate to the SimpleCatalog instance. This approach follows the pattern used
for registering tables with the SQLContext.
Is this the best approach?
