Remove redundant dependencies

[Celebrate-future]

Hi, I am a user of project org.apache.metamodel:MetaModel-hadoop:5.3.3-SNAPSHOT. I found that its pom file introduced 93 dependencies. However, among them, 9 libraries (9%) have not been used by your project (the redundant dependencies are listed below). Reduce these useless dependencies can help prevent conflicts between library versions. MeanWhile, it can minimize the total added size to projects. Finally, it can help enable advanced scenarios for users of your package.
This PR helps org.apache.metamodel:MetaModel-hadoop:5.3.3-SNAPSHOT lose weight :) I have tested the revised configuration in my local environment. It is safe to remove the unused libraries.

Best regards
