我在 Azure 数据工厂的自托管集成运行时中遇到错误，特别是java.lang.NoClassDefFoundError:org/apache/log4j/Level. 这是 ADF 生成的完整错误：

特别是在对 Parquet 文件执行复制活动时。
我可以看到 log4j jar 在 Integration Runtime Jars 目录中：
除了建议以下内容的Informatica 片段外，我还没有找到任何好的文档：
Informatica Data Replication (IDR) 使用了 3 个 lo4j*.jar 文件，如下所示：
- log4j-1.2.16.jar
- log4jdbc3-1.2beta2.jar
- log4jdbc4-1.2beta2.jar
要解决此问题，请确保 DBSYNC_HOME\lib 目录中的三个 Java 文件可用，然后重新运行 IDR 控制台。
有没有人遇到过这个错误？我在自托管机器上运行 Microsoft Integration Runtime v5.0。我认为 slf4j-log4j12-1.7.5 会涵盖这种依赖关系，我错过了什么吗？
