为什么flink 提交job后 task 一直是 schedule 状态

flink-1.11.2 ./bin/start-cluster.sh 启动然后 ./bin/flink run examples/streaming/SocketWindowWordCount.jar --hostname localhost --port 1111

但是 jobmanger 页面 task 一直是 scheduler 状态，过了一段那时间后输出错误

2021-06-18 13:34:26,683 INFO org.apache.flink.runtime.executiongraph.ExecutionGraph [] - Source: Socket Stream -> Flat Map (1/1) (7fc37b6f2e20170da9d95a9b2 28577f2) switched from SCHEDULED to FAILED on not deployed. org.apache.flink.runtime.jobmanager.scheduler.NoResourceAvailableException: Could not allocate the required slot within slot request timeout. Please make sure tha t the cluster has enough resources. at org.apache.flink.runtime.scheduler.DefaultScheduler.maybeWrapWithNoResourceAvailableException(DefaultScheduler.java:441) ~[flink-dist_2.11-1.11.2.jar:1 .11.2] at org.apache.flink.runtime.scheduler.DefaultScheduler.lambda$assignResourceOrHandleError$6(DefaultScheduler.java:422) ~[flink-dist_2.11-1.11.2.jar:1.11.2

但是 slot 资源是有的。我在其他的机器上执行这种操作是正常的。

有大神帮助解释一下吗？*来自志愿者整理的flink邮件归档
