Sunil G commented on YARN-4909:
-------------------------------

Yes [~Naganarasimha Garla]
We need that to be random number.

{{9998 + rnd. nextInt()%500}}, something like this.. So it can be random when called in parallel. However this is not fully solving, there can be corner cases. But probability is very very less.
