Flink Jira Bot updated FLINK-13649:
-----------------------------------
Priority: Minor (was: Major)
> Improve error message when job submission was not successful
> ------------------------------------------------------------
>
> Key: FLINK-13649
> URL: https://issues.apache.org/jira/browse/FLINK-13649
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Web Frontend
> Reporter: Timo Walther
> Priority: Minor
> Labels: auto-deprioritized-major
>
> When submitting a job jar in the web frontend, a user only gets "Internal
> server error" when something went wrong.
> For example, submitting a batch job with {{ExecutionEnvironment env =
> ExecutionEnvironment.createCollectionsEnvironment();}}.
> The logs show a better error message:
> {code}
