Zili Chen commented on FLINK-13417: ----------------------------------- Hello Stephan, the situation is actually flink-runtime uses zookeeper(flink-mesos used a wrapper version of curator's shared value which satisfy use through a utility way) so thay I think the way you proposed is worth to try. However, there's one prerequisite of this way. That's we need to bump curator-test to 4.x(related FLINK-10052) because curator-test 2.x uses zk 3.4 for starting server so that create container message from zk 2.5 client cannot be identified. > Bump Zookeeper to 3.5.5 > ----------------------- > > Key: FLINK-13417 > URL: https://issues.apache.org/jira/browse/FLINK-13417 > Project: Flink > Issue Type: Improvement > Components: Runtime / Coordination > Affects Versions: 1.9.0 > Reporter: Konstantin Knauf > Priority: Major > Fix For: 1.10.0 > > > User might want to secure their Zookeeper connection via SSL. > This requires a Zookeeper version >= 3.5.1.
