jobManager尝试向resourceManager请求152个插槽，但rm没有足够的插槽，最终导致失败。当插槽不再可用时，resourceManager不能从其他taskmanagers获得更多插槽吗？
可用插槽的数量为numberOfTaskmanagersxtaskmanager.numberOfTaskSlots(例如，75个任务管理器有2个插槽，结果是150个插槽(。Flink本身不能触发任何类型的动态缩放。您所能做的就是手动启动更多的任务管理器，或者更改任务管理器配置并重新启动任务管理器。
如果您的任务管理器在作业运行时死亡，您可以定义重新启动策略(请记住，您需要为此启用检查点(：https://ci.apache.org/projects/flink/flink-docs-stable/dev/task_failure_recovery.html#restart-策略
如果你的任务经理死了，没有重新启动，这很可能是一个纱线问题。
