-------------------------------------
Summary: Upgrade curator
Key: FLINK-29173
URL: https://issues.apache.org/jira/browse/FLINK-29173
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.15.2, 1.16.0
Reporter: Matthias Pohl
FLINK-28078 revealed a bug in curator's LeaderLatch implementation that is
covered by CURATOR-645. FLINK-28078 came up with a workaround in
{{ZooKeeperMultipleComponentLeaderElectionDriverTest.testLeaderElectionWithMultipleDrivers}}
(see
[655184c|https://github.com/apache/flink/commit/655184cdb086ac2adec3e743701868f1a55b6129]
{{master}} and
[ed8700d|https://github.com/apache/flink/commit/ed8700d03cccc47bfa39da5e1e6611eb9be7d5a1]
for {{release-1.15}}) that should get reverted after the curator version was
bumbed to a version that includes CURATOR-645.
There's a similar issue CURATOR-644 which we didn't run into but we might want
to observe and include as well, probably.
