macOS上zookeeper运行延迟5秒
在mac新搭了一个zookeeper环境。为java-web提供服务。服务器使用tomcat7.0。zookeeper版本为3.4.6。配置文件zoo没问题，启动正常，在运行zkCli.sh时延时5秒启动。tomcat启动时每一个dubbo接口的注册都需要5秒钟 导致项目部署时间超过两分钟。网上没有找到解决办法。我认为主要在于zookeeper连接本地时那5秒造成的原因。请各位帮助。不胜感激 有人帮忙解答一下吗 YxN 发表于 2016-12-20 20:56有人帮忙解答一下吗
这个需要看下zookeeper的启动日志。应该记录了启动过程。楼主可以分析下 easthome001 发表于 2016-12-20 21:20

谢谢回答。配置文件和日志都翻烂了，没有问题。 项目启动时无报错。就是在dubbo接口注册的时候 一条一条的特别慢，每5秒钟注册一个dubbo的service接口。明天到单位把日志贴出来。
同事在mac 10.11上正常。在自己的win本上也正常。
还是感谢您的回复。

虽然提示了，这应该不是错误。

虽然提示了，这应该不是错误。
我的情况是这样的：
macos第一次安装完成zookeeper后，./zkServer.sh start-foreground正常启动。项目用的是dubbo服务框架，向zookeeper注册服务。然后其他项目调用服务。第一次项目运行都是正常的。
但是macos重启之后，zookeeper启动就已经会有延迟，会卡在读取zoo.cfg文件大概5秒钟。然后再启动项目向zookeeper注册服务的时候，注册一个服务很慢很慢，而且zookeeper会报错
EndOfStreamException: Unable to read additional data from client sessionid 0x0, likely client has closed socket
at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:228)
at org.apache.zookeeper.server.NIOServerCnxnFactory.run(NIOServerCnxnFactory.java:203)
at java.lang.Thread.run(Thread.java:745)
虽然从结果来看，服务也已经注册成功了，但之后调用服务的时候，会报超时错误。
这个问题已经困扰我很多天了，希望不吝赐教。谢谢！

我的项目也是这种情况，在windows下运行正常，但是在mac下总是报错
