-------------------------------------
Summary: Upgrading Flink's default ZooKeeper version to 3.8.3
Key: FLINK-33628
URL: https://issues.apache.org/jira/browse/FLINK-33628
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.19.0
Reporter: Matthias Pohl
Flink currently supports ZooKeeper 3.7.1 as its default version which was added
in Flink 1.17 (FLINK-29420). The ZooKeeper project released 3.8 and 3.9 in the
meantime. 3.7 will reach its EOL with a new minor release. ZooKeeper 3.8 is
already provided by \{{flink-shaded}} and, therefore, allows most likely an
easy switch.
This issue is about chaning to ZooKeeper 3.8.3. A final discussion should be
initiated in the mailing list before merging the change.
