Sushanth Sowmyan reassigned HIVE-16642:
---------------------------------------
> New Events created as part of replv2 potentially break replv1
> -------------------------------------------------------------
>
> Key: HIVE-16642
> URL: https://issues.apache.org/jira/browse/HIVE-16642
> Project: Hive
> Issue Type: Sub-task
> Components: repl
> Reporter: Sushanth Sowmyan
> Assignee: Sushanth Sowmyan
>
> We have a couple of new events introduced, such as
> {CREATE,DROP}{INDEX,FUNCTION} since the introduction of replv1, but those
> which do not have a replv1 ReplicationTask associated with them.
> Thus, for users like Falcon, we potentially wind up throwing a
> IllegalStateException if replv1 based HiveDR is running on a cluster with
> these updated events.
> Thus, we should be more graceful when encountering them, returning a
> NoopReplicationTask equivalent that they can make use of, or ignore, for such
> newer events.
> In addition, we should add additional test cases so that we track whether or
> not the creation of these events leads to any backward incompatibility we
> introduce. To this end, if any of the events should change so that we
> introduce a backward incompatibility, we should have these tests fail, and
> alert us to that possibility.
