> Root Exception not shown in Web UI
> ----------------------------------
>
> Key: FLINK-15917
> URL: https://issues.apache.org/jira/browse/FLINK-15917
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.9.2, 1.10.0
> Reporter: Gary Yao
> Assignee: Gary Yao
> Priority: Critical
> Fix For: 1.10.0
>
>
> *Description*
> On the job details page in the Exceptions → Root Exception tab, exceptions
> that cause the job to restart are not displayed.
> This is already a problem since 1.9.0 if
> {{jobmanager.execution.failover-strategy: region}} is configured,
> which we do in the default flink-conf.yaml.
> *Workarounds*
> Users that run into this problem can set {{jobmanager.scheduler: legacy}}
> and unset {{jobmanager.execution.failover-strategy}} in their
> {{flink-conf.yaml}}
> *How to reproduce*
> In {{flink-conf.yaml}} set {{restart-strategy: fixed-delay}} so enable job
> restarts.
> {noformat}
> $ bin/start-cluster.sh
> $ bin/flink run -d examples/streaming/TopSpeedWindowing.jar
> $ bin/taskmanager.sh stop
> {noformat}
> Assert that no exception is displayed in the Web UI.
> *Expected behavior*
> The stacktrace of the exception should be displayed. Whether the exception
> should be also shown if only a partial region of the job failed is up for
> discussion.
