> When System.out and System.err are redirected to LOG or discarded, there are
> some scenarios that do not match the user's expectations, leading them to be
> unclear about how to view the relevant output information
> # SREs that maintain Flink clusters set all jobs to be redirected or
> discarded by default
> # There are multiple maintainers for the same task, one of them set to
> redirect and the rest are not aware of it.
> Situations such as the above can cause users to add System.out or System.err
> related output, but there is no related output when viewing the out or err
> file, and they don't know the reason for this and don't know where to view
> the related output information.
>
> So we can add tips to optimize these situations, the effect is as follows:
