hadoop - HBase异常

Question

在伪集群模式下使用HBase时，出现以下异常。如果有人能够解决这个问题，那将真的很棒

Answer 1

此问题的根本原因在于/ etc / hosts文件中。如果您检查/ etc / hosts文件，则会找到类似以下条目的条目(在我的情况下，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的主机是理想的

::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，youwanttogive域名解析为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为192.168.58.10，因此创建了以下/ etc / hosts配置；

127.0.0.1 localhost
192.168.43.3 domainnameyouwanttogive

以下行对于支持IPv6的主机是理想的

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

这样可以确保在本地主机上正确完成主机进程的解析，并且可以在开发系统上正确启动HBase安装。

并且请确保您的hadoop namenode以与用于hbase的相同域名运行
