Description

Need to support running REPL LOAD command from primary for different use-cases such as Cloud replication (for efficient use of cloud resources) or workload management.

To achieve this, WITH clause of REPL LOAD lets user to pass Hive configs such as hive.metastore.warehouse.dir, hive.metastore.uris, hive.repl.replica.functions.root.dir etc, which can be used to establish connection with replica warehouse.

The configs received from WITH clause of REPL LOAD are not set properly (due to changes by HIVE-18716) to the tasks created. It is also required to re-get the Hive db object if the configs are changed.
