> Hadoop-3.3 will be released soon, which brings the most important and long awaited Protobuf upgrade to 3.7, by shading the internal protobuf classes in Hadoop-thirdparty library, still keeping the protobuf-2.5.0 as a transitive dependency.
> Unfortunately, There are direct usages of Hadoop's internal protobuf classes. Because of this, ozone breaks after upgrading hadoop dependency to 3.3.0
> This Jira intends to do avoid such direct usages of hadoop's protobuf classes.
