yarn.nodemanager.resource.memory-mb
//每个NodeManager可以供yarn调度(分配给container)的物理内存,单位MB
yarn.nodemanager.resource.cpu-vcores
//每个NodeManager可以供yarn调度(分配给container)的vcore个数
yarn.scheduler.maximum-allocation-mb
//每个container能够申请到的最大内存
yarn.scheduler.minimum-allocation-mb
//每个container能够申请到的最小内存,如果设置的值比该值小,默认就是该值
yarn.scheduler.increment-allocation-mb
//container内存不够用时一次性加多少内存 单位MB。默认512M
yarn.scheduler.minimum-allocation-vcores
//每个container能够申请到的最小vcore个数,如果设置的值比该值小,默认就是该值
yarn.scheduler.maximum-allocation-vcores
//每个container能够申请到的最大vcore个数。
yarn.nodemanager.pmem-check-enabled
//是否对contanier实施物理内存限制,会通过一个线程去监控container内存使用情况,超过了container的内存限制以后,就会被kill掉。
yarn.nodemanager.vmem-check-enabled
//是否对container实施虚拟内存限制
