expected '<document start>', but found BlockMappingStart in 'reader', line 13, column 1:nimbus.host:

具体错误信息如下：

解决方案：
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: "10.10.10.10"空格storm.zookeeper.port: 2181空格storm.local.dir: "date/storm-2.2.1/data"空格supervisor.slots.ports:

大家配置storm.yaml时一定要注意了。
