The number of requested virtual cores for application master 1 exceeds the maximum number of virtual cores 0 available in the Yarn Cluster.

各位好，再请教一个问题哈
mac上部署flink standalone，在运行 bin/flink run -m yarn-cluster 
$FLINK_HOME/examples/streaming/SocketWindowWordCount.jar --port 8882之后提示The 
number of requested virtual cores for application master 1 exceeds the maximum 
number of virtual cores 0 available in the Yarn Cluster.




这是什么问题呢？
