<![CDATA[<p>A distributed implementation of {@link
|
|
org.apache.hadoop.fs.FileSystem}. This is loosely modelled after
|
|
Google's <a href="http://research.google.com/archive/gfs.html">GFS</a>.</p>
|
|
|
|
<p>The most important difference is that unlike GFS, Hadoop DFS files
|
|
have strictly one writer at any one time. Bytes are always appended
|
|
to the end of the writer's stream. There is no notion of "record appends"
|
|
or "mutations" that are then checked or reordered. Writers simply emit
|
|
a byte stream. That byte stream is guaranteed to be stored in the
|
|
order written.</p>]]>
