Matthias Pohl commented on FLINK-30484:
---------------------------------------
This issue has the same cause as FLINK-28078: CURATOR-645 causes it because
we're reusing the LeaderLatch client. We could add a sleep (similar to how it
got fixed in FLINK-28078), or stop reusing the LeaderLatch client.
Alternatively, we could just upgrade to curator 5.4.0 where CURATOR-645 is
fixed (FLINK-29173).
