Apache Druid

By default the druid core classloader is searched first for a class.

But you can try using `druid.extensions.useExtensionClassloaderFirst` (ref : <https://druid.apache.org/docs/latest/configuration/index.html#extensions>) which forces to check the extension CL first

<@U03B0DYSLUF> Are these guava deps by any chance ?
The other way is to shade the deps in your extension pom.

These are some hadoop/hive dependencies which are of a different version compared to the core druid ones. Let me test out the `druid.extensions.useExtensionClassloaderFirst` property and see how it goes, thank you!

just FYI, druid 25.0.0 also has a Hadoop-3 compatible build. <https://www.apache.org/dyn/closer.cgi?path=/druid/25.0.0/apache-druid-25.0.0-hadoop3-bin.tar.gz>
