> Key: HIVE-19499
> URL: https://issues.apache.org/jira/browse/HIVE-19499
> Project: Hive
> Issue Type: Sub-task
> Components: HiveServer2, repl
> Affects Versions: 3.0.0
> Reporter: Sankar Hariappan
> Assignee: Sankar Hariappan
> Priority: Major
> Labels: DR, pull-request-available, replication
> Fix For: 3.1.0
>
>
> 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 hash of 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.
