当我在伪集群模式下使用 HBase 时，出现以下异常。如果有人能对这个问题有所了解以解决它，那就太好了

此问题的根本原因在于您的 /etc/hosts 文件。如果你检查你的 /etc/hosts 文件，你会发现一个类似下面的条目（在我的例子中，mu 机器被命名为 domainnameyouwanttogive）

127.0.0.1 localhost
127.0.1.1 domainnameyouwanttogive

以下行对于支持 IPv6 的主机是可取的

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

根本原因是 domainnameyouwanttogive 解析为 127.0.1.1 这是不正确的，因为它应该解析为 127.0.0.1（或外部 IP）。由于我的外部 IP 是 192.168.58.10 我创建了以下 /etc/hosts 配置；

127.0.0.1 localhost
192.168.43.3 domainnameyouwanttogive

以下行对于支持 IPv6 的主机是可取的

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

这将确保您的 localhost 上的主机进程解析将正确完成，并且您可以在开发系统上正确启动 HBase 安装。

并且请确保您的 hadoop namenode 使用与您用于 hbase 的域名相同的域名运行
