>
> Recently a user ran a job with many vertices, and there was a bug in the
> user's code that caused a problem in one of the trailing vertices in the
> task. On some nodes enough tasks failed that the AM thought it needed to
> blacklist those nodes. That blacklisting then caused many completed vertices
> to re-run because it thought it needed to re-execute the non-leaf tasks that
> had completed on those nodes. This wasted a lot of cluster resources and job
> time for no benefit.
