----------------------------------
Hi, [~fan_li_ya] More details needed, an example will be helpful.
> Improve debuggability of method invocation failures in
> OptimizerPlanEnvironment
> --------------------------------------------------------------------------------
>
> Key: FLINK-12259
> URL: https://issues.apache.org/jira/browse/FLINK-12259
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.8.0
> Reporter: Gaurav
> Assignee: Liya Fan
> Priority: Minor
>
> In cases where method invocation fails without setting the `optimizerPlan`,
> Flink does not always dump the stderr/stdout. Hence, logging from the method
> is lost. The stacktrace alone is not always helpful.
