storm由丰富的configure选项， 用来调整nibus、supervisor、以及运行时topologies的行为。某些配置选项是系统配置，例如topology基础配置，修改某个topology的这些选项有可能影响到所有topologies，而某些选项只是涉及到每个topology自身的配置，这就可以根据需要修改了。
每个配置选项在Storm代码库中的defaults.yaml文件中都有它的默认值。你可以通过定义Nimbus和supervisor的classpath下storm.yaml文件进行覆盖默认配置。最后， 可以定义topology-specific配置，这样你就可以使用StormSubmitter类提交topology时一块提交这个配置文件。然而，
topology-specific配置仅能覆盖前缀为“TOPOLOGY”的配置选项。
从Storm 0.7.0开始，你可以覆盖每一个bolt或者每个spout自己特有的配置选项。这些配置如下所示：
1、"topology.debug"
2、"topology.max.spout.pending"
3、"topology.max.task.parallelism"
4、"topology.kryo.register"：这个选项和其他选项的作用方式有点不同， 因为序列对topology中的所有组件都是可用的。 更多信息可以查看序列化。
Java API 允许你使用两种方式制定组件的特定配置选项：
1、 内部方式： 在任何spout或者bolt中覆盖getComponentConfiguration，然后返回component-specific配置映射。
2、 外部方式： TopologyBuilder类中setSpout方法和setBolt方法会返回带有addConfiguration以及addConfigurations方法的对象，这个对象可以用来覆盖组件的配置选项。
配置选项值的推荐顺序是： defaults.yaml < storm.yaml < topology specific configuration <internal component specific configuration < external component specificconfiguration
