> Key: FLINK-30183
> URL: https://issues.apache.org/jira/browse/FLINK-30183
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Affects Versions: 1.16.0
> Reporter: Matthias Pohl
> Assignee: Matthias Pohl
> Priority: Major
> Labels: pull-request-available, starter
>
> A [user reported an
> issue|https://lists.apache.org/thread/yjv0hof5qqnzq22xcjf3y2v61j48gqh4] with
> the {{PrometheusReporter}} instantiation. The {{NoSuchMethodException}} is
> caused by the {{PromethusReporter}} not having a default constructor
> implemented. Instead, the user should switch to the factory class approach.
> We might want to -log a warning if the reflection-based approach still works
> but- wrap the {{NoSuchMethodException}} into a
> {{IllegalConfigurationException}} with a proper error message pointing to the
> factory-based approach
