Coursera: Hadoop Platform and Application Framework

 with  Natasha Balac, Paul Rodriguez and Andrea Zonca
This course is for novice programmers or business people who would like to understand the core tools used to wrangle and analyze big data. With no prior experience, you will have the opportunity to walk through hands-on examples with Hadoop and Spark frameworks, two of the most common in the industry. You will be comfortable explaining the specific components and basic processes of the Hadoop architecture, software stack, and execution environment. In the assignments you will be guided in how data scientists apply the important concepts and techniques such as Map-Reduce that are used to solve fundamental problems in big data. You'll feel empowered to have conversations about big data and the data analysis process.

Syllabus

Hadoop Basics
Welcome to the first module of the Big Data Platform course. This first module will provide insight into Big Data Hype, its technologies opportunities and challenges. We will take a deeper look into the Hadoop stack and tool and technologies associated with Big Data solutions.

Introduction to the Hadoop Stack
In this module we will take a detailed look at the Hadoop stack ranging from the basic HDFS components, to application execution frameworks, and languages, services.

Introduction to Hadoop Distributed File System (HDFS)
In this module we will take a detailed look at the Hadoop Distributed File System (HDFS). We will cover the main design goals of HDFS, understand the read/write process to HDFS, the main configuration parameters that can be tuned to control HDFS performance and robustness, and get an overview of the different ways you can access data on HDFS.

Introduction to Map/Reduce
This module will introduce Map/Reduce concepts and practice. You will learn about the big idea of Map/Reduce and you will learn how to design, implement, and execute tasks in the map/reduce framework. You will also learn the trade-offs in map/reduce and how that motivates other tools.

Spark
Welcome to module 5, Introduction to Spark, this week we will focus on the Apache Spark cluster computing framework, an important contender of Hadoop MapReduce in the Big Data Arena. Spark provides great performance advantages over Hadoop MapReduce,especially for iterative algorithms, thanks to in-memory caching. Also, gives Data Scientists an easier way to write their analysis pipeline in Python and Scala,even providing interactive shells to play live with data.

I am enrolled and almost done with this course. I cannot wait to get done! I have taken many other courses on Coursera, and this one is the worst. I do not feel that it is giving me a true sense of what Hadoop or big data is all about, nor any "hands on" practice on applications to real world projects. Read More
I am enrolled and almost done with this course. I cannot wait to get done! I have taken many other courses on Coursera, and this one is the worst.

There is no feedback from instructors or mentors who normally respond to posts from other students requesting help or information. The only feedback seems to be from a few other interested students taking the course. And, most of the posts on the discussion board are outdated, giving the impression that there is no one else is taking the course.

The quizzes ask a student to "Choose all that apply". Most of the questions are in this format. I understand that an auto-grader usually does not give partial credit for partially correct answers, but there lies a huge disadvantage in even taking these quizzes if there is no feedback provided. Such is the case in the format of the quizzes for this course.

Additionally, the quizzes have nothing to do with the course content. I practically had to google every question to find out what I needed. You will learn more if you get a copy of the quizzes and research the answers for yourself.

Taking this course forced me to decipher through inaudible videos whose instructors mumble off of the bullet points in their slides. I have never given a Coursera course a bad review, but this one deserves it.

Definitely better than the "Introduction to Big Data", but still miles away from what I consider a decent course. What's the point in presenting slides and reading the keywords to students? What's the point in handing out those slides instead of "real" documents (compare the ideas of Garr Reynolds or Nancy Duarte on that issue)? What's the point in testing for simple facts? On the bright side: The hands-on assignments were kind of fun, although I fear some people may get frustrated as some background in programming definitely helps - should be made clear in the syllabus, I think.

Not worth my time, and definitely not worth the price if you are considering doing the specialization.

I felt I was tricked into this specialization. Not much content, lots of repeats. Definitely not worth the money. $10, ok. but no penny more. I dropped out and got a refund.

Most troubling is the lack of responses from Coursera staff and UCSD lecturers. Silence from all sides.

The Course videos are poor in content and in explaining what the tools do. The Quizzes ask questions that have not been covered in the video material and the programming assignments are in many cases unrelated to what is explained in the videos, instructions are unquestionably useless in many cases and you are expected to know how to to program. I can't quite understand how they would be so bold to say it is for business people (i.e. a high level course with minimal programming knowledge).

Certainly not worth the cost of the course. If I had not already paid for it I would drop and make better use of my time and money.

You are left to your own as the only help you get is that of other students and the posts they put. There is no way how to contact the instructors.

Sam K dropped this course.
Very poorly delivered course. I have some exposure to Hadoop and thought this course would give a full stack in-depth hands on experience as this is a total 7 months specialization. But dropped out and was lucky to get a refund. Very superficial coverage of the course and very poorly delivered. The presenters just read from a poorly prepared slide content.

Brian O. is taking this course right now.
The course is presented by 2 lecturers at UCSD. The Hadoop lectures were bullet points recited from Powerpoint slides. The required assignments presume working knowledge of Python that was not disclosed prior to enrollment. The Spark lectures were abysmal; none of the bullet points recited were explained or expounded upon. I would not recommend this class to anyone.

Kumar Np is taking this course right now.
I am almost done with this course. Thouroughly disappointed with the course content. It is too basic and high level. I have exposure to hadoop, reason for taking this course was to gain structured knowledge at least at an intermediate level, which did not happen. Lecturers just readout the slides, no insight into any of the content.

However, it does provide a good overview of the different components in the Hadoop ecosystem, and did provide a good guidance for further studies into these tools.

It is a beginner course, so has to be valuated as is. It help the student to know the basic tools and concepts in the hadoop eco system. Quizzes are good if taken seriously and you really understand if you grasp the concepts. Was one of the first course online that I take, so I have no terms to compare to, but yes, it is absolutely missing some interaction with the tutors.

One of the worst courses I have taken.

Don't waste your time. My head was filled with the Hadoop stack and what I need is Map and reduce the information this course provides. A lot of slides without pointing out the essence.

The team is not involved at all in he discussions.

The assignments degree of difficulty/complexity are not related with the few "bla, bla, bla" they talk about in the course. So I had to spend many many many hours learning in internet what I had to know for completing the assignments. And of course because they did not answer to any of the students questions

The material offered for learning is no a joke is even worse.

I really recomend some other course not Coursera San Diego
