> We are potentially hitting an in-memory-shuffle-related reservation
> starvation resembling MAPREDUCE-6445. To work it around, we wanted to disable
> in memory shuffle via mapreduce.reduce.shuffle.memory.limit.percent=0.0 that
> turned out to be disallowed by the current logic. So we had to resort to
> another small float value such as 0.0001. However, zero is more logical imo.
