All Implemented Interfaces:

Closeable, Configurable

public final class SingleStreamFileSystem
extends FileSystem

Very simple Filesystem Implementation which serves an InputStream for a given path. This is used to serve the underlying input stream from a FileSystem Interface. Only open() and getFileStatus() is implemented.
