> When use assignMultiple，and such as set maxAssign=10:
> if a job is high CPU util or high CPU load, it may lead to  a part of nodes   very busy. and the job may cost a long time.
> so , i want to limit the max containers to assign to one application per heartbeart, it may help to nodes use more uniform.
