----------------------------------------------
Summary: Enforce single maxExceptions query parameter
Key: FLINK-32198
URL: https://issues.apache.org/jira/browse/FLINK-32198
Project: Flink
Issue Type: Bug
Components: Runtime / REST
Reporter: Panagiotis Garefalakis
While working on FLINK-31894 I realized that `UpperLimitExceptionParameter`
allows multiple values to be collected as a comma separated list even though
JobExceptionsHandler is only using the first one
[https://github.com/apache/flink/blob/1293958652053c0d163fde28e8dfefb5ee8f6101/flink-runtime/src/main/java/org/apache/flink/runtime/rest/handler/job/JobExceptionsHandler.java#L101-L104]
A better approach would be to deny multiple `maxExceptions` params and let the
users know.
