Question

我有三个节点来启动Hbase集群，但它无法启动HMenter和Regionservers，例外情况如下：

FATAL [main] regionserver.RSRpcServices: The hostname of regionserver cannot be set to localhost in a fully-distributed setup because it won't be reachable. See "Getting Started" for more information.
2015-04-05 09:11:58,160 ERROR [main] master.HMasterCommandLine: Master exiting

有人说区域服务器的主机名是Localhost。但事实并非如此，我的两个regionservers的主机名分别是dev1.test.local和dev2.test.local。我还在配置文件RegionServers中指定了IP。我很好奇为什么HMaster认为RegionServer的主机名是localhost？提前致谢！

在hbase 1.0中，您无法将master添加为区域服务器。

Hbase启动失败，因为regionserver的主机名无法设置为localhost
