[jira] [Updated] (FLINK-12382) HA + ResourceManager exception:
Fencing token not set
[ https://issues.apache.org/jira/browse/FLINK-12382?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Henrik updated FLINK-12382:
---------------------------
Description:
I'm testing zetcd + session jobs in k8s, and testing what happens when I kill both the job-cluster and task-manager at the same time, but maintain ZK/zetcd up and running.
Then I get this stacktrace, that's completely non-actionable for me, and also resolves itself. I expect a number of retries, and if this exception is part of the protocol signalling to retry, then it should not be printed as a log entry.
This might be related to an older bug: [https://jira.apache.org/jira/browse/FLINK-7734]

tm stands for taskmanager in this deployment.
EDIT: this also happens if you just temporarily disable network routing; it never recovers on its own despite having HA configured! In this case, it's the job manager that keeps crashing.

> Key: FLINK-12382
> URL: https://issues.apache.org/jira/browse/FLINK-12382
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.8.0
> Environment: Same all all previous bugs filed by myself, today, but this time with HA with zetcd.
> Reporter: Henrik
> Priority: Major
>
> I'm testing zetcd + session jobs in k8s, and testing what happens when I kill both the job-cluster and task-manager at the same time, but maintain ZK/zetcd up and running.
> Then I get this stacktrace, that's completely non-actionable for me, and also resolves itself. I expect a number of retries, and if this exception is part of the protocol signalling to retry, then it should not be printed as a log entry.
> This might be related to an older bug: [https://jira.apache.org/jira/browse/FLINK-7734]
> {code:java}

> tm stands for taskmanager in this deployment.
> EDIT: this also happens if you just temporarily disable network routing; it never recovers on its own despite having HA configured! In this case, it's the job manager that keeps crashing.
