Big Data With Hadoop

What is Big Data with Hadoop ?

Hadoop is an open source software project that enables the distributed processing of large data sets across clusters of commodity servers. Hadoop changes the economics and the dynamics of large scale computing. Big Data with Hadoop training and expertise impact can be boiled down to four salient characteristics. For obvious reason Hadoop certified professional are enjoying now huge demand all over the world with fat pay package and growth potential where sky is the limit.

Our Approach:

Students are at the top of our priority list and we always make sure that every student is given the best training possible. In order to provide the best training, all our training modes have been made interactive sessions.

The student will be connecting to our Live virtual classroom where they will be able interact with the trainer.

We provide one of the best professional trainings within SAP in the industry. The courses are run by experts with ample industry experience on this subject matter. The course run are well up to professional standards with the latest  industry updates. Contact our team at Jenrac Technologies for all your queries.

By the end of this training you will:
- Understand the core concepts of Big Data module.
- Be able to apply the knowledge learned to progress in your career as an Big Data Developer.

Minimum knowledge of OOP languages like Core Java, python, Ruby. Recommended/Additional
Experience in the above mentioned languages is recommended but not essential.

Classroom Training: An Instructor led training in our dynamic learning environment based in our office at West London. The classroom is fitted with all the essential amenities needed to ensure a comfortable training experience and with this training you will have an opportunity to build a Networking with other learners, share experiences and develop social interaction.
