Question

我按照有点简单的http://hbase.apache.org/book/quickstart.html安装Hbase 0.94.2，但它还没有工作。运行启动脚本我进入日志文件：

2012-11-23 18:26:37,827 INFO org.apache.zookeeper.ClientCnxn: Session establishment complete on server localhost/127.0.0.1:2181, sessionid = 0x1

这是一个Ubuntu 12.04 LTS VirtualBox，1GB内存，10GB可用磁盘空间，带有Oracle JRE 1.6.0_37。

我找到了一些关于/ etc / hosts的解决方法，但我不确定它们是否相关。我的etc / hosts仅包含：

127.0.0.1   localhost
127.0.1.1   'my-host-name'

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

非常感谢任何帮助或推荐到专门的HBase论坛！谢谢！

好的，这很简单，在/ etc / hosts中只更改了127.0。 1 .1到127.0。 0 .1，所以现在解析了本地主机名到后者，而不是前者。 Hbase快速回答的论坛是http://apache-hbase.679495.n3.nabble.com/，在这里得到了很好的回答。不确定为什么这种改变是必要的。

HBase无法启动
