Stamatis Zampetakis commented on HIVE-26205:
--------------------------------------------
I am using maven 3.6.3 and the compilation does not fail. Any ideas of why it
fails only with maven 3.8.5?
> Remove the incorrect org.slf4j dependency in kafka-handler

> *Root cause:*
> The `pom.xml` of `kafka-handler` module defines such dependency:

> <!-- kafka-handler/pom.xml -->
> <dependency>
> <groupId>org.slf4j</groupId>
> <artifactId>slf4j-api</artifactId>
> <scope>test</scope>
> </dependency>
> {code}
> which causes that log4j lib can be available only in test. It is a redundant
> config that we can remove.
