# Step-by-step

Checkout Hadoop (branch-0.14):
  * `git clone -b branch-0.14 https://github.com/arquivo/hadoop-common`

Install Hadoop:
(compile with JAVA 8 and maven 3)
  * `cd hadoop-common`
 * `mvn install`
<li><ul><blockquote>This version of Hadoop (<a href='http://hadoop.apache.org/'>http://hadoop.apache.org/</a>) must be used for all mapreduce processing.<br>
Checkout PwaLucene + PwaArchiveAccess:<br>
</blockquote>
</ul></li>
* `git clone https://github.com/arquivo/pwa-technologies.git`

Install PwaLucene:<br>
(compile with JAVA 6 and maven 2)
</li><li><code>cd pwa-technologies/PwaLucene</code>
</li><li><code>mvn install</code>
Install PwaArchiveAccess:<br>
</li><li><code>cd pwa-technologies/PwaArchive-access</code>
(compile with JAVA 8 and maven 3)
</li><li><code>mvn install</code>
</li><li><a href='https://github.com/arquivo/pwa-technologies/wiki/ConfigureSearch'>configure </a> (only if you need to change the default configuration)
</li><li><code>mvn install</code></li></ul>
