Review comment:
```suggestion
return Sets.newHashSet(new TaskSlotIterator(jobId,
TaskSlotState.ACTIVE))
.stream()
.map(TaskSlot::getAllocationId)
.collect(Collectors.toSet());
```
The only other shorter way I can imagine is the one above. I just hesitated
because it would mean iterating over the collection twice just to save a few
lines.
