---------------------------------------
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.
