> The graph has several sources, only one of which is fully finished (i.e. all
> subtasks).
> All sources have setUidHash set.
> The latter I think causes the problem:
> VerticesFinishedCache.checkOperatorFinished uses a hashmap of opertor states,
> keyed by operator ID. It prefers user-defined ID falling back to a generated
> one.
> However, the map seems to be always keyed by generated ID.
