Hi Sweta,
there was a non-compatible change to SourceReaderContext#metricGroup in
the 1.14.x release line; I assume this is what you are seeing.
Did you make sure to update the connector (and any other) dependencies
as well?

Hi,
We are on flink 1.13.3 and trying to upgrade the cluster to 1.14.3
version. I see that job(on 1.13.3) is unable to start up because it says
it couldn't find metrics group(inside flinkkafkaconsumer class).
- can I deploy 1.13.3 job on 1.14.3 cluster?
- can I deploy 1.14.3 job on 1.13.3 cluster?
- How do I upgrade to 1.14.3 cluster without loosing running apps state?
I have even tried doing savepoint that did not revive the job.
Thank you,
Sweta
