> GetTablesOperation is too slow since it does not check for the authorization for databases
and try pulling all the tables from all the databases using getTableMeta. for operation like
follows
> {code}
> con.getMetaData().getTables("", "", "%", new String[] \{ "TABLE", "VIEW" });
> {code}
> build the getTableMeta call with wildcard *
> {code}
>  metastore.HiveMetaStore: 8: get_table_metas : db=* tbl=*
> {code}
