工人日志中的连接拒绝错误-Apache Storm [英] Connection refused error in worker logs - apache storm

问题描述

我在工作日志中看到以下错误，该错误几乎每毫秒发生一次，但是群集运行良好，我想知道这些错误是什么意思，以及关于为什么会发生这种情况的任何想法.

I see the below error in worker logs, it happens almost every milliseconds, but the cluster is running fine, I wanted to know what does these error mean and any idea on why this would occur.

这在所有工作节点上发生

This happens on all the worker nodes

一段时间后，我看到了 2016-05-12T15:44:25.940-0500 bsmnClient [错误]丢弃1条消息，因为Netty-Client-xxxxx.hq.abc.com/xx.xx.xxx.xxx:6700的Netty客户端已关闭

推荐答案

在为这个问题苦苦挣扎之后，我发现在storm.yaml文件中设置storm.local.hostname属性可以为我解决该问题.在我的笔记本电脑上，将storm.zookeeper.servers，nimbus.host和storm.local.hostname都设置为"localhost".

After struggling forever with this problem, I found that setting storm.local.hostname property in the storm.yaml file solved the issue for me. On my laptop, I set storm.zookeeper.servers, nimbus.host and storm.local.hostname all to "localhost".

我正在使用Storm的0.10.2版本.

I am using version 0.10.2 of storm.
