Review Comment:
This is refactoring. This reordering was earlier being done in
scheduleExecutorsOnNodes(). But it should be done when the executors are
sorted. Then Round Robin strategy to can override scheduleExecutorsOnNodes()
and still receive the executors sorted in right order (i.e. ackers at the end)
