CERTIFIED BIGDATA PROFESSIONAL ANALYSIS
R is an open source software package to perform statistical analysis on data while Apache Hadoop is an open source Java framework for processing and querying vast amounts of data on large clusters of commodity hardware.
R is a programming language used by data scientist statisticians to make statistical analysis of data and glean key insights from data using mechanisms, such as regression, clustering, classification, and text analysis.
Hadoop changes the economics and the dynamics of large-scale computing. Its impact can be boiled down to four salient characteristics. Hadoop enables scalable, cost-effective, flexible, fault-tolerant solutions. Now comes the question comes Why combine R and Hadoop?
The strengths of R lie in its ability to analyze data using a rich library of packages but fall short when it comes to working on very large datasets. The strength of Hadoop on the other hand is to store and process very large amounts of data in the TB and even PB range. Such vast datasets cannot be processed in memory as the RAM of each machine cannot hold such large datasets. The options would be to run analysis on limited chunks also known as sampling or to correspond the analytical power of R with the storage and processing power of Hadoop and you arrive at an ideal solution.
IVY Global Academy is the only organization that offers this unique certification with dual benefit.
This certification is great for R developers who are looking for a way to perform Big Data analytics with Hadoop.
The exam comprises of 80 Multiple Choice Questions out of which the candidate needs to score 70% (56 correct out of 80 Questions) to pass the exam. The total duration of the exam is 1 hour 30 Min (90 Minutes). Exams are online and can be taken anywhere anytime. All you need is a reliable internet connection. The exam is conducted in a closed book manner. No external sources of information may be accessed during the exam. The certification is valid for life and does not require renewal.
Repeat attempt policy
If a candidate does not pass the exam in the first attempt, the candidate must wait for a period of at least fourteen (14) calendar days from the date of the attempt to retake the exam for second (2nd) time or any subsequent time. The exam can be taken any number of times.
You should have sound knowledge on both R and Hadoop.
