Hadoop Introduction:

Hadoop is referred as an open source software. By hadoop, large sets of data are transferred among many computers on the server by using simple programming methods. Hadoop is outlined to rise up from a single server to thousands of computers with a very high percentage of availability. Handling failures in the application are determined by the software itself instead of some hardware. Our online course training provides you an ample knowledge of operating the Hadoop software through various challenges in the IT field.
