yanghua commented on issue #6567: [FLINK-10074] Allowable number of checkpoint
failures

@azagrebin thanks for your suggestion, I agree and reconsider more details.
Considering that @tillrohrmann has said that the current checkpoint
exception handler should also be implemented in `CheckpointCoordinator`.
> I understand why you implemented it the way you did. I think the
`setFailOnCheckpointingErrors` should actually also be handled by the
`CheckpointCoordinator`/`JM` and not on the Task level (but this is a different
story). This looks a little bit like a shortcut we made back in the days.
Do we need to take this refactoring into account? Because this PR is
actually a supplement to the checkpoint exception handler.

> For intermittent checkpoint failures it is desirable to have a mechanism to
> avoid restarts. If, for example, a transient S3 error prevents checkpoint
> completion, the next checkpoint may very well succeed. The user may wish to
> not incur the expense of restart under such scenario and this could be
> expressed with a failure threshold (number of subsequent checkpoint
> failures), possibly combined with a list of exceptions to tolerate.
