        Runs the main method of class with the specified arguments.
        The jstorm jars and configs in $JSTORM_CONF_DIR/storm.yaml are put on the classpath.
        The process is configured so that StormSubmitter
        (https://github.com/alibaba/jstorm/wiki/JStorm-Chinese-Documentation)
        will upload the jar at topology-jar-path when the topology is submitted.

    错误原因是:在打jar包的时候,把jstorm-core这个jar包也包含进去了,如下图:
    这里写图片描述

    打包时,移除该jar,再次部署即可。

    或者:
    在pom文件中修改storm-core的scope为provided

    <dependency>
        <groupId>org.apache.storm</groupId>
        <artifactId>storm-core</artifactId>
        <version>1.1.0</version>
         <!--本地调试的时候,屏蔽掉scope,等打包部署的时候再放开-->
        <scope>provided</scope>
    </dependency>

    这样在idea打包时,就不会包含改 jar了。

    小注:
    provided是表明了dependency 由JDK或者容器提供,例如Servlet AP和一些Java EE APIs。这个scope 只能作用在编译和测试时,同时没有传递性。
