[jira] [Created] (HIVE-19499) Bootstrap REPL LOAD shall add tasks to create checkpoints for tables/partitions.
Sankar Hariappan created HIVE-19499:
Summary: Bootstrap REPL LOAD shall add tasks to create checkpoints for tables/partitions.
Issue Type: Sub-task
Components: HiveServer2, repl
Affects Versions: 3.0.0
Reporter: Sankar Hariappan
Assignee: Sankar Hariappan
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.
