What is Hadoop technology?

Answer 1

     We have computer servers used in many applications including web applications.  They have huge amount of data in their databases.  The servers have usually multiple processors too.  Apache Hadoop technology introduces the concept of distributed File system for splitting the data into chunks and then storing them on many computers.   So Hadoop technology is basically distributed computing.   It is beneficial as a lot of parallel processing takes place and the large number of client requests over the network are shared by multiple computers, coordinated by the central server.
 
    Hadoop is a free software from Apache Foundation.
