Question

我正在使用Zookeeper Hazelcast发现，但是现在我将其更改为Hazelcast-Kubernetes。似乎工作正常，但有时它会显示警告消息，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.

我找不到OPT等之类的协议用法。

我应该如何清除此警告？

注意：

我正在使用openshift，并且我的spring boot应用程序在一个名称空间下的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());

此GH Issue中有类似的问题报告。如此处所述，添加以下部分可能会解决问题：

- containerPort: 5701

无论如何，它可能是hazelcast-kubernetes的错误。随时将“重现步骤”添加到以下Hazelcast Kubernetes GH Issue中。
