Question

我有一个以下示例flink应用程序，我试图在群集上运行。

public class ClusterConnect {
public static void main(String[] args) throws Exception {
    ExecutionEnvironment env = ExecutionEnvironment

.createRemoteEnvironment（＆＃34; X.X.X.X＆＃34;，6123，＆＃34;＆＃34;）;

    // get input data
    DataSet<String> text = env.fromElements("To be, or not to be,--that is the question:--",
            "Whether 'tis nobler in the mind to suffer", "The slings and arrows of outrageous fortune",
            "Or to take arms against a sea of troubles,");

    DataSet<Tuple2<String, Integer>> counts = text
            .flatMap(new FlatMapFunction<String, Tuple2<String, Integer>>() {
                @Override
                public void flatMap(String s, Collector<Tuple2<String, Integer>> collector) throws Exception {
                    for (String word : s.split(" ")) {
                        collector.collect(new Tuple2<String, Integer>(word, 1));
                    }
                }
            })
            .groupBy(0)
            .sum(1);

    // execute and print result
    counts.print();
    env.execute();
}

群集设置有一个jobmanager（免费aws实例）和两个任务管理器（免费aws实例）。尝试在不同的AWS（可能会到达jobmanager，taskmanagers）上运行上述flink应用程序时，会出现以下错误。

申请时出错：

WARN  [akka.remote.ReliableDeliverySupervisor] Association with remote system [akka.tcp://flink@172.31.29.190:6123] has failed, address is now gated for [5000] ms. Reason is: [Disassociated].

来自群集作业管理器的日志：

无法在群集上运行flink应用程序
