---------------------------------
[~dwysakowicz] No, the UI part is still open which is covered by FLINK-21867.
[~vthinkxie] is there a chance for you to pick it up?

> Users requested that it would be nice to see the last {{n}} exceptions
> causing a job restart in the Web UI. This will help to more easily debug and
> operate a job.
> We could store the root causes for failures similar to how prior executions
> are stored in the {{ExecutionVertex}} using the {{EvictingBoundedList}} and
> then serve this information via the Web UI.
> _-- Update: January 21, 2021 --_
> The UI can already handle multiple exceptions through the Exception History.
> Right now, we list one or more exceptions which caused the job to fail.
> Instead, we could adapt it in a way that the history contains not only the
> exceptions of the most recent failure but one expandable entry per restart.
> If there are more than one exception connected to a single restart, we would
> list their stacktraces within one expandable entry.
