--------------------------------
Summary: 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
Fix For: 1.11.0, 1.10.1
*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}} in their {{flink-conf.yaml}}
*How to reproduce*
In {{flink-conf.yaml}} set {{restart-strategy: fixed-delay}} so enable job restarts.

$ 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.
