Victor Wong commented on FLINK-15449:
-------------------------------------
Nice suggestion! We could add the constructed log URL (the Yarn container log
URL) to Flink UI.
> Retain lost task managers on Flink UI

> Key: FLINK-15449
> URL: https://issues.apache.org/jira/browse/FLINK-15449
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / YARN
> Affects Versions: 1.9.1
> Reporter: Victor Wong
> Priority: Major
>
> With Flink on Yarn, sometimes our TaskManager was killed because of OOM or
> heartbeat timeout or whatever reasons, it's not convenient to check out the
> logs of the lost TaskManger.
> Can we retain the lost task managers on Flink UI, and provide the log service
> through Yarn (we can redirect the URL of log/stdout to Yarn container
> log/stdout)?
