Flink運行過程中報：

org.apache.flink.runtime.jobmanager.scheduler.NoResourceAvailableException: Could not allocate enough slots within timeout of 300000 ms to run the job. Please make sure that the cluster has enough resources.

解決方案：

調整Flink里面flink-conf.yaml里面的新增參數增加可支持的slot數量

taskmanager.network.memory.fraction: 0.1

taskmanager.network.memory.min: 268435456

taskmanager.network.memory.max: 4294967296
