flink启动同步任务后全部失败，报错：NoResourceAvailableException: Could

Caused by: java.util.concurrent.CompletionException: java.util.concurrent.CompletionException: org.apache.flink.runtime.jobmanager.scheduler.NoResourceAvailableException: Could not acquire the minimum required resources.
    at org.apache.flink.runtime.scheduler.DefaultExecutionDeployer.lambda$assignResource$4(DefaultExecutionDeployer.java:226)
 

办理：修改flink的配置文件 ，目次是 flink-1.18.0/conf/中flink-conf-yaml的jobmanager.memory.process.size和taskmanager.memory.flink.size。
如修改为
jobmanager.memory.process.size: 5600m
taskmanager.memory.flink.size: 6280m
然后重启flink服务 ./bin/stop-cluster.sh，重启同步任务。
注意：实际修改后还是报错，发现配置前面多了个空格⊙﹏⊙，删掉后重启服务成功。。配置时要仔细查抄。
