ROLE OF HADOOP IN INFORMATION TECHNOLOGY

ABSTRACT

Nowadays, Companies need to process Multi Petabyte Datasets efficiently. The Data may not have strict schema for the large system. It has become Expensive to build reliability in each Application for processing petabytes of datasets. If there is a problem of Nodes fail every day, some of the causes of failure may be. Failure is expected, rather than exceptional. The number of nodes in a cluster is not constant. So there is a Need for common infrastructure to have Efficient, reliable, Open Source Apache License. The Hadoop platform was designed to solve problems where you have a lot of data perhaps a mixture of complex and structured data and it doesn
