             Summary: Fix unset db params for optimized bootstrap incase of data copy tasks run on target and testcases
                 Key: HIVE-26598
                 URL: https://issues.apache.org/jira/browse/HIVE-26598
             Project: Hive
          Issue Type: Bug
            Reporter: Teddy Choi
            Assignee: Rakshith C


when hive.repl.run.data.copy.tasks.on.target is set to false, repl dump task will initiate the copy task from source cluster to staging directory.

In current code flow repl dump task dumps the metadata and then creates another repl dump task with datacopyIterators initialized.

when the second dump cycle executes, it directly begins data copy tasks. Because of this we don't enter second reverse dump flow and  unsetDbPropertiesForOptimisedBootstrap is never set to true again.

this results in db params (repl.target.for, repl.background.threads, etc) not being unset.
