异常:
REDUCE capability required is more than the supported max container capability in the cluster. Killing the Job. reduceResourceRequest: <memory:12160, vCores:1> maxContainerCapability:<memory:8192, vCores:24>
需要调整两个参数:
yarn.nodemanager.resource.memory-mb
yarn.scheduler.maximum-allocation-mb
注意:如果只设置其中一个,可能依然存在同样的报错
