> In case of a non-standalone recovery mode, the job manager frontend of non-leading job
managers prints the job manager information of its associated job manager. Because the job
manager is not leading, nothing shows up.
> The web frontend cannot directly communicate with the leading job manager, because many
job manager structures like the execution graph are not serializable.
> A work around is to redirect to the web frontend of the leading job manager. This makes
sure that all interesting information is presented.
