---------------------------------------
Summary: 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.
