Homework Answers
Hadoop is a software architecture which is used for the Big Data application.Its features are:
It provides the reliable storage layer.
It is Fault tolerant
It has got high availability.
It has got Fast Processing capability.
It is highly Scalable we can add any number of nodes vertically or horizontally to increase the processing power of Hadoop.
Comin to the architecture point of view it is composed mainly of three components:
HDFS : It is the data storage layer of Hadoop.
Map Reduce : It is the Processing layer of Hadoop mainly distributed processing.
YARN : It is the resource management layer of Hadoop and responsible for resource allocation and job scheduling.
Main functionality of Hadoop is maing the huge data into meaningful information.and distributed file system for clusters of data so that it can be accessed parallely
