Did you restart slurmctld after changing 

Also your nice values are too small. It is not unix nice. Its range is 
+/-2147483645, and it race with other priority factors at priority 
factor formula. Look priority factor formula at 

Because of that, I think you should test with very high numbers for low 
priority nice such as --nice 100000.
