I'm not actively working on it; I can assign it to you. You basically have to
do the thing you proposed for Flink, just against the
[flink-shaded|https://github.com/apache/flink-shaded/] repo.
I would then close this ticket as a duplicate.

> We occasionally hit an issue where our Flink cluster will not startup if any
> of the zookeeper hosts passed in the "high-availability.zookeeper.quorum"
> config setting are unreachable. This seems to stem from us using an older
> zookeeper dependency version (3.4.10).
> Sample error we see is shown below.
> This error seems to stem from us being on an older zookeeper release
> (3.4.10). This has been fixed as part of:
> https://issues.apache.org/jira/browse/ZOOKEEPER-1576 in the 3.4.x branch
> ([https://github.com/apache/zookeeper/commit/be1409cc9a14ac2e28693e0e02a0ba6d9713565e]).
