Attila Doroszlai commented on HDDS-6626:
----------------------------------------
[~kerneltime],
These thirdparty jars (hadoop-shaded-guava, hadoop-shaded-protobuf) are
distributed by Hadoop. We do not include a specific version of Hadoop jars in
Ozone FS jar to allow using any compatible Hadoop version. The application
provides Hadoop jars and only needs to add Ozone FS jar to the classpath. A
newer Hadoop version may bump its version of thirdparty libs. By including a
specific version of these (specifically hadoop-shaded-protobuf) in the Ozone FS
jar, the application using newer Hadoop may run into classloading problems.

> Shaded Ozone FS jars currently include Hadoop Thirdparty libs. This can
> result in version mismatch if the FS jars are used with different Hadoop
> version than the one we package with (3.3.1 currently). Hadoop Thirdparty
> libs should be excluded and provided by the user, similar to regular Hadoop
> libs (hadoop-common, hadoop-hdfs-client, etc.).
