1、遇到Producer connection to hostname:9092 unsuccessful

 解决办法:

    寻找linux下的/etc/hosts和window下的C:\Windows\System32\drivers\etc\hosts所有IP地址与主机名是否配置正确。

    最后发现一个低级错误,window下的hostname配置IP地址错误了。

 

192.168.0.36    hadoop.main
192.168.0.146   hadoop.slave1
192.168.0.142   slave001
192.168.146   master001

 注意:192.168.146   master001
