Sobre o curso

Interested in increasing your knowledge of the Big Data landscape? This course is for those new to data science and interested in understanding why the Big Data Era has come to be. It is for those who want to become conversant with the terminology and the core concepts behind big data problems, applications, and systems. It is for those who want to start thinking about how Big Data might be useful in their business or career. It provides an introduction to one of the most common frameworks, Hadoop, that has made big data analysis easier and more accessible -- increasing the potential for data to transform our world! At the end of this course, you will be able to: * Describe the Big Data landscape including examples of real world big data problems including the three key sources of Big Data: people, organizations, and sensors. * Explain the V’s of Big Data (volume, velocity, variety, veracity, valence, and value) and why each impacts data collection, monitoring, storage, analysis and reporting. * Get value out of Big Data by using a 5-step process to structure your analysis. * Identify what are and what are not big data problems and be able to recast big data problems as data science questions. * Provide an explanation of the architectural components and programming models used for scalable big data analysis. * Summarize the features and value of core Hadoop stack components including the YARN resource and job management system, the HDFS file system and the MapReduce programming model. * Install and run a program using Hadoop! This course is for those new to data science. No prior programming experience is needed, although the ability to install applications and utilize a virtual machine is necessary to complete the hands-on assignments. Hardware Requirements: (A) Quad Core Processor (VT-x or AMD-V support recommended), 64-bit; (B) 8 GB RAM; (C) 20 GB disk free. How to find your hardware information: (Windows): Open System by clicking the Start button, right-clicking Computer, and then clicking Properties; (Mac): Open Overview by clicking on the Apple menu and clicking “About This Mac.” Most computers with 8 GB RAM purchased in the last 3 years will meet the minimum requirements.You will need a high speed internet connection because you will be downloading files up to 4 Gb in size. Software Requirements: This course relies on several open-source software tools, including Apache Hadoop. All required software can be downloaded and installed free of charge. Software requirements include: Windows 7+, Mac OS X 10.10+, Ubuntu 14.04+ or CentOS 6+ VirtualBox 5+....

I love the course. It goes deep into the foundations, and then finishes up with an actual lab where you learn by practice. I greatly benefited from it and feel I have achieved a milestone in big data.

In this course, I learned how to use Hadoop basically. With the clear explanation of the Professor, I believe every one can realize in a short time.

i would like to see more intermittent testing and application of my knowledge. it felt like it had a high ratio of lecture to hands-on/testing/etc

The beginning is a bit theoretical, only the end brings some practical examples up. Slides are a bit old fashioned and presenters are a bit rigid

Great content, very broad and provides a good overview of BigData. They alloy you to taste the subject and try a "Hands on" approach at the end.

This is probably the best Introduction to Hadoop. Minus 1 star only because I wish I could receive the sessions on mail for future reference.

Increase the depth on hands on exercises. There were very basic and did not explore even all the examples which hadoop provides by default!

If more case studies and writing MapReduce programs using Python are added to the last section of the course, it would be awesome.

A little slow to start, but probably good to understand the whole picture. The hands on Hadoop is A+ for me as a beginner.

To me, I feel there're too many common senses were talked about. Would be much better if we go strait to the key points...

It would have been nice to understand how to delete directories in Hadoop so that the final exercise was more productive.
