QUESTION
I'm trying to understand if behaviour of the flink jobmanager during zookeeper upgrade is expected or not.
I'm running flink 1.11.2 in kubernetes, with zookeeper server 3.5.4-beta. While I'm doing zookeeper upgrade, there is a 20 seconds zookeeper downtime. I'd expect to either flink job to restart or few warnings in the logs during those 20 seconds. Instead, I see whole flink JVM crash ( and later the pod restart).
I expected for flink to internally retry zookeeper requests, so I'm surprised it crashes. Is this expected, or is it a bug?
From the logs
...ANSWER
Answered 2021-Feb-11 at 17:20If a zookeeper quorum is maintained during the upgrade, then the Flink job manager should not be impacted. Otherwise it's not surprising that the job manager would fail.
Normally you would upgrade the zookeeper followers first, one by one, and then upgrade the leader last. Verify that the quorum has been reestablished before taking down another node.

Answered 2020-Apr-29 at 07:26You use the commands for Hazelcast (and Management Center) version 4.0
, but you actually run images 3.12.5
. The mechanism how Management Center is connected has changed. So you need to either use the most recent version or apply the instructions for 3.12.5, like this:
