Description

What would you like to be improved?

Current Gravitino virtual filesystem (filesystem-hadoop3) module only builds against Hadoop 3, doesn't have a shim layer to support multiple Hadoop versions. it is better to filesystem-hadoop3 module to support multiple Hadoop versions.

How should we improve?

I think we can refer to several projects to build a shim layer to support multiple Hadoop versions if necessary.

Contributor guide

Research direction
Review existing Hadoop version shim implementations in similar projects and plan how to integrate a shim layer into the Gravitino filesystem hadoop3 module.
