hadoop - HBase 区域服务器 : error telling master we are up

Question

我在从属 RegionServer 的日志中收到以下错误。问题似乎出在

regionserver.HRegionServer: reportForDuty to master=localhost,60000,1397430611631 with port=60020

master 设置为 localhost 但实际上应该指向 master。即使在阅读了文档之后，我也无法弄清楚奴隶是如何弄清楚主人的。

完整日志为:

检查你的/etc/hosts 文件，如果有类似的东西

127.0.0.1 localhost yourhost

改成

127.0.0.1 localhost
192.168.1.1 yourhost
