Storm提交Topology运行方式分为本地和集群运行两种，其中集群运行需要将程序打包并把jar包复制到集群，通过以下方式执行：
bin/storm jar /opt/run/storm-demo-1.0-SNAPSHOT-jar-with-dependencies.jar org.mort.storm.kafka.KafkaTopologyBasic
bin/storm jar [jar包路径] [main所在类名]
不过有时程序运行报错提示如下：
Caused by: java.lang.RuntimeException: java.io.IOException: Found multiple defaults.yaml resources. You‘re probably bundling the Storm jars with your topology jar. [jar:file:/opt/run/storm-demo-1.0-SNAPSHOT-jar-with-dependencies.jar!/defaults.yaml, jar:file:/opt/module/apache-storm-1.2.3/lib/storm-core-1.2.3.jar!/defaults.yaml] at org.apache.storm.utils.Utils.findAndReadConfigFile(Utils.java:385) at org.apache.storm.utils.Utils.readDefaultConfig(Utils.java:429) at org.apache.storm.utils.Utils.readStormConfig(Utils.java:465) at org.apache.storm.utils.Utils.<clinit>(Utils.java:179) ... 39 more Caused by: java.io.IOException: Found multiple defaults.yaml resources.

出现问题原因是storm-core下面也存在一个defaults.yaml文件，因此storm运行时报错冲突，因此修改Maven配置文件，添加scope属性并设为provided：
<dependency>
<groupId>org.apache.storm</groupId>
<artifactId>storm-core</artifactId>
<version>1.2.3</version>
<scope>provided</scope>
</dependency>
scope设置成provided表示容器或JDK已提供范围，表示该依赖包已经由目标容器（如tomcat）和JDK提供，只在编译的classpath中加载和使用，打包的时候不会包含在目标包中。
再次运行成功提交。
