             Summary: Bootstrap REPL LOAD to use checkpoints to validate and skip the loaded DB/tables/partition objects.
                 Key: HIVE-19739
                 URL: https://issues.apache.org/jira/browse/HIVE-19739
             Project: Hive
          Issue Type: Sub-task
          Components: HiveServer2, repl
    Affects Versions: 3.0.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan
             Fix For: 4.0.0


Currently. bootstrap REPL LOAD expect the target database to be empty or not exist to start bootstrap load.

But, this adds overhead when there is a failure in between bootstrap load and there is no way to resume it from where it fails. So, it is needed to create checkpoints in table/partitions to skip the completely loaded objects.

Use the fully qualified path of the dump directory as a checkpoint identifier. This should be added to the table / partition properties in hive via a task, as the last task in the DAG for table / partition creation.
