WARN org.apache.zookeeper.ClientCnxn: Session 0x0 for server null

Question

`

 我估计是ZOOKEEPER启动不起来，请大家帮我看看是什么原因，我研究了两天了，实在不知道怎么弄了

使用文件如下：

CentOS_5.5_Final.iso

jdk-6u35-linux-i586.bin

hadoop-0.20.2-cdh3u2.tar.gz

hbase-0.94.0.tar.gz

[Hadoop@chen hbase-0.94.0]$ vi logs/hbase-Hadoop-master-chen.ran.log 中出现了如下警告信息，使用list查hbase也不成功

为什么会出现：

 

 

 

[Hadoop@chen hbase-0.94.0]$ bin/start-hbase.sh

Hadoop@master 's password:

查看日志是zookeeper没起来
