Description

First get all the database names and their locations.

1. Create Table Task for each database by providing the db name
2. DB Task will get the names and locations for all the tables in that database.

1. Create Partition task for each table in that database by providing the database and table names.
   1. Table task will get the locations of all the partitions in that table.

This approach needs new API’s implemented in HMS to get the names and locations of the databases/tables/partitions.
