We are working on B.Tech project and we want to build dummy Custom Distributed File system for hadoop.
In 2.5.1 version there are 2 classes : 1) FileSystem and 2) AbstractFileSystem. To make our own custom DFS which one of these two classes should we implement or extend to our custom filesystem class. Because in earlier version there was only FileSystem class. Can you please tell us what is difference between FileSystem and AbstractFileSystem classes and when to use each one sand which one should we implement in our case? Thanks, Vikrant
