             Summary: 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


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)?
