Description

Catalog by default pulls in all the tables from HMS. Impala however, only can work with some table formats. Such tables are shown in the table listing and when they are queries, Impala also loads them. It is only during querying that we throw an error saying its an unsupported table format. It would be good to have a config which can take in list of storage handlers and skip loading such tables.
