110	<P>
111	An abstract base class for a fairly generic filesystem. It
112	may be implemented as a distributed filesystem, or as a "local"
113	one that reflects the locally-connected disk. The local version
114	exists for small Hadoop instances and for testing.
115
116	<p>
117
118	All user code that may potentially use the Hadoop Distributed
119	File System should be written to use a FileSystem object. The
120	Hadoop DFS is a multi-machine system that appears as a single
121	disk. It's useful because of its fault tolerance and potentially
122	very large capacity.
123
124	<p>
125	The local implementation is <A HREF="../../../../org/apache/hadoop/fs/LocalFileSystem.html" title="class in org.apache.hadoop.fs"><CODE>LocalFileSystem</CODE></A> and distributed
126	implementation is DistributedFileSystem.
