我正在按照有点简单的http://hbase.apache.org/book/quickstart.html安装 Hbase 0.94.2 ,但它还没有工作。运行我在日志文件中得到的启动脚本:

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。

我发现了一些关于 /etc/hosts 的解决方法,但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

任何帮助或推荐到专门的 HBase 论坛将不胜感激!谢谢!

好的,这很简单,在 /etc/hosts 中只更改了 127.0. 1 .1 至 127.0。0 .1,所以现在本地主机名被解析为后者,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。不知道为什么这个改变是必要的。
