Special Note:


        ** No need to install any other third party module like Java module Kit, My sql, Xamp etc.
          But if you have sql server 2005/2008, My Sql already installed than you can use them instead of Embaded database as
          we have chosen during configuration of Database.
       
        ** When we install Spark in Windows 7 or Server 2008; we should allow it through firewall both Public & Private Category.
