Why Enroll for Big Data and Hadoop at IIHT?

Whenever there is a discussion on Big Data, it is very unlikely that Hadoop doesn’t come into the picture. Though Big Data is a broader concept than Hadoop, Hadoop has become such an integral part of Big Data that many a times both these concepts are used synonymously. Interestingly, at IIHT, students not only learn Hadoop (HDFS and MapReduce) but also other tools related to Big Data such as Spark, Hive, Pig and Latin, HBase, Sqoop, YARN and Hadoop Security.

Don’t know Java? Not to worry at all! IIHT’s engineering programme in Big Data and Hadoop begins with the fundamentals of Java that will equip with the required skills to understand Hadoop concepts with ease!

To your surprise, Hadoop skills are one of the top skills in demand in 2016 and in coming years. Many companies are looking out for professionals who can demonstrate Hadoop skills as well as related Technologies included in our programme.

If career progression is on your mind, IIHT’s high-end Big Data and Hadoop programme is the ideal choice for you as well as for employers!
