             Summary: JarRunHandler ignores restore mode set in the configuration
                 Key: FLINK-28651
                 URL: https://issues.apache.org/jira/browse/FLINK-28651
             Project: Flink
          Issue Type: Bug
          Components: Runtime / REST
    Affects Versions: 1.15.1, 1.15.0
            Reporter: Nuno Afonso


Hello all,

 

I started a Flink cluster with execution.savepoint-restore-mode set to CLAIM. Then, I submitted a job through the REST API without specifying restoreMode in the request. I would expect Flink to use CLAIM, but the job used NO_CLAIM as restore mode.

 

After looking into the source code, I believe the issue comes from the way JarRunHandler picks the default for restoreMode. It directly gets it from the default of execution.savepoint-restore-mode instead of looking into the existing configuration: [https://github.com/apache/flink/blob/release-1.15.1/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/handlers/JarRunHandler.java#L150]

 

I think the fix can be achieved by getting execution.savepoint-restore-mode from the configuration.

 

Looking forward to hearing your feedback.
