HBase 独立版无法连接（无法创建表）

我正在尝试在本文之后以独立模式部署Hbase：http://hbase.apache.org/book.html#quickstart。版本为 0.92.1-cdh4.1.2

但是我在尝试创建表时遇到这些错误：

错误信息：

    13/04/01 14:07:10 ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries
13/04/01 14:07:10 WARN zookeeper.ZKUtil: hconnection Unable to set watcher on znode /hbase/master

输出日志：

我的配置：

1. 在 hbase-env.sh 中添加JAVA_HOME

2. hbase_site.xml

   <name>hbase.rootdir</name>
   
   <value>file:///home/hadoop/data</value>
   

   <name>hbase.zookeeper.property.dataDir</name>
   
   <value>file:///home/hadoop/zookeeper</value>
   

我试图修改/etc/hosts，它看起来像这样（oracle是主机名）：

127.0.0.1   localhost oracle

或

[server ip]   localhost oracle

但这些对我不起作用。

我的确切代码是：

[usr@oracle bin]$ ./start-hbase.sh 
starting master, logging to /home/hadoop/hbase-0.94.6/bin/../logs/hbase-usr-master-oracle.out
[usr@oracle bin]$ hbase shell

提前致谢！
