由于多个log4j错误,storm拓扑提交失败。
在本地Eclipse中,它起作用了。但在storm集群中提交拓扑时,拓扑提交失败。
我使用的是storm版本1.1.1和kafkaè2.9.2(0.8.1.1)。如何在eclipse中通过maven找到来自jars的log4j文件?

在日 eclipse 中,在 Dependency Hierarchy 视图,过滤log4j,slf4j jars。
观察到其他一些依赖jar也有log4j slf4j jar。
排除所有重复jar后,重新生成应用程序。
现在没有发现重复的jar,并且能够提交拓扑。
所以去看看maven Dependency Hierarchy 查看并删除重复的jar。
