+<div class="section">
+<p>
+        Hadoop archives are special format archives. A Hadoop archive
+        maps to a FileSystem directory. A Hadoop archive always has a *.har
+        extension. A Hadoop archive directory contains metadata (in the form 
+        of _index and _masterindex) and data (part-*) files. The _index file contains
+        the name of the files that are part of the archive and there location
+        within the part files. 
+        </p>
+</div>
+        
+<a name="N10017"></a><a name="How+to+create+an+archive%3F"></a>
+<h2 class="h3"> How to create an archive? </h2>
+<div class="section">
+<p>
+        
+<span class="codefrag">Usage: hadoop archive -archiveName name &lt;src&gt;*
&lt;dest&gt;</span>
+        
+</p>
+<p>
+        -archiveName is the name of the archive you would like to create. An example would
be 
+        foo.har. The name should have a *.har extension. The inputs are filesystem pathnames
which 
+        work as usual with regular expressions. The destination directory would contain the
archive.
+        Note that this is a Map Reduce job that creates the archives. You would need a map
reduce cluster
+        to run this. The following is an example:</p>
+<p>
+        
+<span class="codefrag">hadoop -archiveName foo.har /user/hadoop/dir1 /user/hadoop/dir2
/user/zoo/</span>
+        
+</p>
+<p>
+        In the above example /user/hadoop/dir1 and /user/hadoop/dir2 will be archived in
the following
+        filesystem directory -- /user/zoo/foo.har. The sources are not changed or removed
when an archive
+        is created.
+        </p>
+</div>
+        
+<a name="N1002F"></a><a name="How+to+look+up+files+in+archives%3F"></a>
+<h2 class="h3"> How to look up files in archives? </h2>
+<div class="section">
+<p>
+        The archives exposes itself as a filesystem layer. So all the fs shell commands in
the archives work but 
+        with a different URI. Also, note that archives are immutable. So, rename's, deletes
and creates return an error. 
+        URI for Hadoop Archives is 
+        </p>
+<p>
+<span class="codefrag">har://scheme-hostname:port/archivepath/fileinarchive</span>
+</p>
+<p>
+        If no scheme is provided it assumes the underlying filesystem. 
+        In that case the URI would look like 
+        </p>
+<p>
+<span class="codefrag">
+        har:///archivepath/fileinarchive</span>

+        <title> What are Hadoop archives? </title>
+        <p>
+        Hadoop archives are special format archives. A Hadoop archive
+        maps to a FileSystem directory. A Hadoop archive always has a *.har
+        extension. A Hadoop archive directory contains metadata (in the form 
+        of _index and _masterindex) and data (part-*) files. The _index file contains
+        the name of the files that are part of the archive and there location
+        within the part files. 
+        </p>
+        </section>
+        <section>
+        <title> How to create an archive? </title>
+        <p>
+        <code>Usage: hadoop archive -archiveName name &lt;src&gt;* &lt;dest&gt;</code>
+        </p>
+        <p>
+        -archiveName is the name of the archive you would like to create. An example would
be 
+        foo.har. The name should have a *.har extension. The inputs are filesystem pathnames
which 
+        work as usual with regular expressions. The destination directory would contain the
archive.
+        Note that this is a Map Reduce job that creates the archives. You would need a map
reduce cluster
+        to run this. The following is an example:</p>
+        <p>
+        <code>hadoop -archiveName foo.har /user/hadoop/dir1 /user/hadoop/dir2 /user/zoo/</code>
+        </p><p>
+        In the above example /user/hadoop/dir1 and /user/hadoop/dir2 will be archived in
the following
+        filesystem directory -- /user/zoo/foo.har. The sources are not changed or removed
when an archive
+        is created.
+        </p>
+        </section>
+        <section>
+        <title> How to look up files in archives? </title>
+        <p>
+        The archives exposes itself as a filesystem layer. So all the fs shell commands in
the archives work but 
+        with a different URI. Also, note that archives are immutable. So, rename's, deletes
and creates return an error. 
+        URI for Hadoop Archives is 
+        </p><p><code>har://scheme-hostname:port/archivepath/fileinarchive</code></p><p>
+        If no scheme is provided it assumes the underlying filesystem. 
+        In that case the URI would look like 
+        </p><p><code>
+        har:///archivepath/fileinarchive</code></p>
+        </section>
+	</body>
