> Flink uses the {{OptimizerPlanEnvironment}} which replaces stdout/stderr during job graph creation. This was intended only for previewing the plan, but other parts of Flink, e.g. the Rest API have started to use this code as well.
> It may be acceptable to suppress output during plan preview, but we should not suppress the output during execution, e.g. via the REST API.
