Description
Initiator shouldn't be fetch table details for all its partitions. When there are large number of databases/tables, it takes lot of time for Initiator to complete its initial iteration and load on DB also goes higher.
For all the following partitions, table details would be the same. However, it ends up fetching table details from HMS again and again.
