当我运行我的风暴拓扑来读取Kafka主题并将数据写入Hive表时，我收到了IllegalAccesserror：错误详情如下：

请帮帮我。 感谢。
答案 0 :(得分：2)
当我尝试在我的风暴群集中部署拓扑时，我遇到了同样的错误：检查并重新检查您提交的所有jar文件是否没有任何风暴可能已经在类路径中提供的重复项。
在我的情况下，一旦我确定slf4j jar不在提交的罐子里，我再次尝试并且它工作得很好。
正如我在您的pom.xml中看到的那样，您必须将log4j范围更改为提供
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
在任何情况下，您还应该检查风暴已经提交了哪些罐子并将其从您的依赖项中删除。
当我在风暴中运行我的拓扑时，风暴会进行此调用：

在这里你可以看到log4j-core-2.1.jar正在暴风雨中提供，产生一个碰撞，导致你看到的异常。请参阅this其他相关问题。
