> I noticed during my work on FLINK-34427 that the reconcilliation is scheduled periodically when starting the {{SlotManager}}. But it doesn't handle errors in this step. I see two options here:
> 1. Fail fatally because such an error might indicate a major issue with the RM backend.
> 2. Log the failure and continue the scheduled task even in case of an error.
> My understanding is that we're just not able to recreate TaskManagers which should be a transient issue and could be resolved in the backend (YARN, k8s). That's why I would lean towards option 2.
> [~xtsong] WDYT?
