Hazelcast Kubernetes 警告未知协议

Question

我使用的是 Zookeeper Hazelcast 发现，但现在我已将其更改为 Hazelcast-Kubernetes。它似乎工作正常，但有时它会打印警告消息，例如：

2020-10-16 13:45:27.434  WARN 1 --- [.IO.thread-in-1] com.hazelcast.nio.tcp.TcpIpConnection    : [10.131.6.73]:5701 [dev] [3.12.7] Connection[id=6, /10.131.6.73:5701->/10.131.6.1:58546, qualifier=null, endpoint=null, alive=false, type=NONE] closed.

和

2020-10-16 13:45:27.438  WARN 1 --- [.IO.thread-in-2] com.hazelcast.nio.tcp.TcpIpConnection    : [10.131.6.73]:5701 [dev] [3.12.7] Connection[id=7, /10.131.6.73:5701->/10.131.6.1:58548, qualifier=null, endpoint=null, alive=false, type=NONE] closed.

             at com.hazelcast.internal.networking.nio.NioThread.run(NioThread.java:235)

我找不到任何协议用法，如 OPT 等。

我应该怎么做才能清除这个警告？

注意：

我正在使用 openshift，并且我的 Spring Boot 应用程序在一个命名空间下的 3 个 Pod 中使用 hazelcast 分布式缓存。

这是我的设置：

config.getNetworkConfig().getJoin().getMulticastConfig().setEnabled(false);
config.getNetworkConfig().getJoin().getAwsConfig().setEnabled(false);
config.getNetworkConfig().getJoin().getTcpIpConfig().setEnabled(false);
        config.getNetworkConfig().getJoin().getKubernetesConfig().setEnabled(true)
            .setProperty("service-name", applicationProperties.getHazelcast().getServiceName())
            .setProperty("namespace", applicationProperties.getPod().getNamespace());

GH Issue 中有类似的问题报告。如那里所述，添加以下部分可能会解决问题：

- containerPort: 5701

无论如何，这可能是hazelcast-kubernetes 的错误。随意将“重现的步骤”添加到以下Hazelcast Kubernetes GH Issue。
