Hadoop is a distributed computing system that works on commodity hardware on a scale and speed that is just not possible for other database processing systems to match. Due to this there is a huge demand for Hadoop Developers who can deploy Hadoop on a massive scale.

A Hadoop Developer is responsible for the actual coding or programming of Hadoop applications. Hadoop developer jobs responsibilities are to write programs as per the system designs and must have fair knowledge about the coding and programming. Task of Hadoop developer is similar to software developer but in Big Data domain. Job of Hadoop developer also includes understanding and working to come up with solutions to problems, designing and architecting along with strong documenting skills.

Training Objectives of Hadoop Developer
The Hadoop Developer online training equips you with the right skill sets needed to take the Professional Hadoop Developer Cloud era Certification. This Hadoop Certification training is your passport to the most sought-after jobs in the Big Data world. Hadoop Developer Certification Training will help you get a detailed idea about Big Data and Hadoop. Some of the topics included are introduction to the Hadoop ecosystem, understanding of HDFS and MapReduce including MapReduce abstraction. Learn to install, implement various components of Hadoop like Pig, Hive, Flume, Sqoop and YARN.

Target Students / Prerequisites:
Anyone interested in Hadoop, HDFS and MapReduce.
For those who want to learn programming in MapReduce a little OOP knowledge is assumed.
Basic database knowledge is assumed. (Like joins, normalization)
