        * slf4j-api-1.6.4
        * zookeeper-3.4.5

    * MyMediaLiteJava Library:
        * mymedialite

    * Custom Library:
        * CommonTools


Description
-----------

    * Hbase Libraries can be found on server, HBase installation lib folder.
    * Phoenix just should be recognized by itself, when Phoenix is properly installed on server.
    * For recommendations is used MyMediaLite Java port version 2.03. https://github.com/jcnewell/MyMediaLiteJava
    * CommonTools contains packages to work with Algorithms, Database and Books.

Servlet deployment
------------------

    * Servlet .war file must be deployed on tomcat server.
        For example, from tomcat manager (http://tomcatUrl/manager) in "WAR file to deploy" section, click Browse,
        choose Servlet .war file from computer and press Deploy.
        Connect to Servlet using link: http://tomcatUrl:port/RecommendationServlet/RecommendationServlet

Using SQL scripts
-----------------

    * Everything works with HBase database, so add tables first.
        execute SQL scripts from sql_scripts.txt one by one.
        * We are now using Apache Phoenix, so connect to it first.
        * GOTO: /home/edgaras/phoenix
            then connect to Putty and in command line type:
                bin/sqlline.py master.pc:2181:/hbase-unsecure

       * Now you'll be able to work with Apache Phoenix.
