Duo Zhang commented on HADOOP-12910:
------------------------------------
Have you guys thought of using something like guava's ListenableFuture or
netty's modified version of Future instead of the jdk's default Future? The
Future in jdk does not support listener so hard to write event-driven code
based on it.
Thanks.

> Add a new API, namely FutureFileSystem (or AsynchronousFileSystem, if it is a
> better name). All the APIs in FutureFileSystem are the same as FileSystem
> except that the return type is wrapped by Future, e.g.
> {code}
> //FileSystem
> public boolean rename(Path src, Path dst) throws IOException;
> //FutureFileSystem
> public Future<Boolean> rename(Path src, Path dst) throws IOException;
> {code}
> Note that FutureFileSystem does not extend FileSystem.
