Jagadesh Adireddi commented on FLINK-24707:
-------------------------------------------
Thank you [~dmvk] for the explanation.
I am under the impression of upgrading ZK and curator to the desired versions
and using the curator client with the _idempotent_ modifier for write
operations (Create, SetData, Delete) would automatically fix the ticket
FLINK-24543
> Upgrade Curator framework dependecy.

> We want to upgrade curator to latest version, to avoid working around
> non-idempotent writes.

> Main reason for not doing this in patch release as part of FLINK-24543 is
> that this effectively drops support for Zookeeper 3.4.x.
> The very last past release two 3.4.x branch was more then two years ago (2
> April, 2019) and there are already three newer minor versions available
> (3.5.x,3.6.x,3.7.x).
