What is Meant by Hadoop :

Hadoop is a type of database: 

  No. Hadoop is not a type of Database.Hadoop isn't a kind of database, yet rather a product biological system that takes into account enormously parallel registering.

Hadoop Background :

With an expansion in the infiltration of web and the utilization of the web, the information caught by Google expanded exponentially year on year.
Just to give you a gauge of this number, in 2007 Google gathered on a normal 270 PB of information consistently.
A similar number expanded to 20000 PB ordinary in 2009. Clearly, Google required a superior stage to process such a gigantic information.
Google executed a programming model called MapReduce, which could process this 20000 PB for every day. Google ran these MapReduce tasks on a unique document framework called Google File System (GFS). Unfortunately, GFS isn't an open source.

Doug cutting and Yahoo! figured out the model GFS and constructed a parallel Hadoop Distributed File System (HDFS). The product or system that backings HDFS and MapReduce is known as Hadoop. Hadoop is an open source and conveyed by Apache.
