Flink Jira Bot updated FLINK-16306:
-----------------------------------
Labels: auto-unassigned stale-major (was: auto-unassigned)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Validate YARN session state before job submission
> -------------------------------------------------
>
> Key: FLINK-16306
> URL: https://issues.apache.org/jira/browse/FLINK-16306
> Project: Flink
> Issue Type: Improvement
> Components: Client / Job Submission
> Affects Versions: 1.10.0
> Reporter: Daniel Laszlo Magyar
> Priority: Major
> Labels: auto-unassigned, stale-major
>
> To better handle not properly stopped yarn sessions, state of the session
> should be validated before job submission.
> Currently if {{execution.target: yarn-session}} is set in
> {{conf/flink-conf.yaml}} and the hidden YARN property file
> {{/tmp/.yarn-properties-root}} is present, FlinkSessionCli tries to submit
> the job regardless of the session’s state.
> Apparently, the property file cannot get cleaned up automatically when the
> session is killed e.g. via {{yarn app -kill <appID>}} and this behaviour is
> pointed out in the logs upon running via yarn-session.sh, but the contained
> application state could be checked before submitting to it. The current
> behaviour feels inconsistent with the scenario when the YARN property file
> actually does get cleaned up e.g. by manually deleting the file, in which
> case a per-job cluster is spun up before submitting to it.
>
> Replication steps:
> • start flink yarn session via {{./bin/yarn-session.sh -d}}, this writes the
> application id to {{/tmp/.yarn-properties-root}}
> • set {{execution.target: yarn-session}} in
> {{/etc/flink/conf/flink-conf.yaml}}
> • kill session via {{yarn app -kill <appID>}}
> • try to submit job, e.g.: {{flink run -d -p 2
> examples/streaming/WordCount.jar}}
> The logs clearly state that the FlinkYarnSessionCli tries to submit the job
> to the killed application:
