有人能解释一下吗？问题是否与端口/防火墙有关，或者某些设置出错？问题在于安全组端口权限。当打开从
0到65565的整个范围时，一切都开始工作。但这对于生产系统来说还不够好，因此最终对于flink-conf.yaml
config文件中的工作人员来说，键taskmanager.data.port
被分配了一个特定的端口，这就成功了。通过这种方式，可以将任务管理器配置为侦听范围内的特定端口 对于这样一个小型集群，ask超时通常意味着您在创建工作期间Flink无法连接到外部系统。例如，某些服务的端口错误或被防火墙阻止。任务管理器日志显示连接到端口39493/34094上的metrics服务器的尝试失败，可能这延迟了心跳响应我添加的整个端口范围为0-65535。这就成功了。但是有没有办法配置或控制这个范围？我尝试配置'taskmanager.rpc.port:50100-50200'，但没有帮助。还有其他参数吗？嗨，你得到解决方案了吗？是的。上面的回答提到了这一点。设置taskmanager.data.port
我正在Kubernetes上运行我的flink群集，并在那里自动分配端口。此外，我尝试为其分配一个特定端口，但收到相同的错误，无法控制请求超时设置。
