flink启动任务时异常，加载不到flink/lib目录下的包

[yujianbo]

环境： flink 1.12.0
报这个错：报加载不到这个log4j-slf4j-impl-2.12.1.jar包，但是我的lib目录下是有这个包的，请问这是什么问题，是有jar包冲突吗，没有头绪？
我的情况是这样的：两套hadoop集群一样的flink包，之前是cdh的hadoop3.0.0，hive是2.2.0；现在准备从cdh迁回社区版的hadoop集群，变成3.3.0，hive是3.1.2，昨天解决了hive-exec的问题，但是今天同样的一份代码在上一个集群是可以正常提交正常跑的，但是放到新的集群这边启动的时候就直接报错加载不到lib包下的一个jar，就有点奇怪，是yarn冲突了吗？

这是我lib下面的包
$ cd lib/
$ ll

我已经解决了，是因为我跑的任务jar包里的resources目录下的一个文件hdfs-site.xml是上一份集群的，我把这个去掉就可以了。

想了解的参考：
