平台：centos-6.3-i386

jdk-7u51

storm 0.9.1

python 2.6.6

hadoop 1.2.1

启动storm的时候，遇到这个问题，百度之后，看到大家的解决方案是在 nimbus.host: "master"前加上空格，但是，我的已经加上空格。还是出错。

查看报警信息标识是在nimbus的n上，经试验原来是这几个配置名称前需要加空格。即：

空格nimbus.host: "192.168.1.101"

空格storm.zookeeper.port: 2181

空格storm.local.dir: "home/hadoop/storm-0.9.1/data"

空格supervisor.slots.ports:

大家配置storm.yaml时一定要注意了。少一个空格竟然就启动不了，真是不可思议。

安装有错误可以在这上面找解决方案
