HBase异常
提问于 2013-02-06 10:34:35
当我在伪集群模式下使用HBase时，我得到了下面的异常。如果有人能解决这个问题，那就太好了。

此问题的根本原因存在于/etc/hosts文件中。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，µ机器被命名为domainnameyouwanttogive)
127.0.0.1 localhost
127.0.1.1 domainnameyouwanttogive以下代码行适用于支持IPv6的主机
::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是错误的，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，所以我创建了以下/etc/hosts配置；
127.0.0.1 localhost
192.168.43.3 domainnameyouwanttogive以下代码行适用于支持IPv6的主机
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters这将确保正确解析本地主机上的主机进程，并且可以在开发系统上正确启动HBase安装。
