+<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>
+
+<span class="codefrag">Usage: hadoop archive -archiveName name <src>* <dest></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>

+<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

+ <section>
+ <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 <src>* <dest></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>
+</document>
