kafka 执行Consumer的时候，发生异常。Could not retri?报错
我在linux端部署了一个zookeeper和kafka服务，都是单个的服务，不是集群。然后我在网上找的producer例子，向topic放入数据是没有问题的，但是我执行Consumer的时候，总是报错。请大神帮忙。

回复 @呼啦_小呆:这个怎么看啊。下面第三个答案是我的配置信息，因为太长了，给你发不了。你帮我看下吧，谢谢了回复 @初级屌丝:看一下你zoo.cfg的配置对不对是不是用得机器名我在Windows端中hosts中已经设置了啊。。。如下#Forexample:#localhostnameresolutionishandledwithinDNSitself.#127.0.0.1localhost#::1localhost10.6.50.53vm-vmw674-t这样设置不对吗我在Windows端中hosts中已经设置了啊。。。如下
#Forexample:
#Thenumberofmillisecondsofeachtick
#
# 102.54.94.97 rhino.acme.com #sourceserver
# 38.25.63.10 x.acme.com #xclienthost
#localhostnameresolutionishandledwithinDNSitself.
#127.0.0.1 localhost
#::1 localhost
10.6.50.53vm-vmw674-t
这样设置不对吗
tickTime=2000
#Thenumberofticksthattheinitial

#Thenumberofticksthatcanpassbetween

这个事zoo.cfg配置文件，你帮我看下，有什么不对吗有一个折中的办法，就是把日志级别由debug改为info和log4j.logger.org.apache.zookeeper=info
我也遇到这样问题改了之后不行2018-02-2717:05:19DEBUG: Gotpingresponseforsessionid:0x161d64b0b380001after3ms
