flink standalone部署， task manager启动失败-问答-阿里云开发者社区-阿里云

搭建flink1.6.2 standalone集群，用start-cluster.sh启动，在task manager总是报错：
Could not resolve ResourceManager address akka.tcp://flink@flink.jm:6123/user/resourcemanager, retrying in 10000 ms: Ask timed out on [ActorSelection[Anchor(akka.tcp://flink@flink.jm:6123/), Path(/user/resourcemanager)]] after [10000 ms]. Sender[null] sent message of type "akka.actor.Identify"..

在task manager上执行：telnet flink.jm 6123，是成功的
请问，这是什么问题？
