課程概述

At the end of the course, you will be able to: *Retrieve data from example database and big data management systems *Describe the connections between data management operations and the big data processing patterns needed to utilize them in large-scale analytical applications *Identify when a big data problem needs data integration *Execute simple big data integration and processing on Hadoop and Spark platforms This course is for those new to data science. Completion of Intro to Big Data is recommended. 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. Refer to the specialization technical requirements for complete hardware and software specifications. 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 (except for data charges from your internet provider). Software requirements include: Windows 7+, Mac OS X 10.10+, Ubuntu 14.04+ or CentOS 6+ VirtualBox 5+....

It was a good course, it could have been better if some examples of Spark were also provided in other Languages like Java, people without having background of python may find it difficult.

As i am not familiar with the VM and its environment, I spent more time struggling with the VM paths, initialization even with the pre command sets than doing the computation of the data.

The course material is not sufficient to work out the exercises. For the Spark final quiz you will have to take up another course to pass this one.

Programming instructions were not clear, and the version of Python that was installed on my machine did not support the Jupy

I wish that the Spark programming should have been covered in more details as was the MongoDB and Splunk covered.

the instructions to the final test are insufficient and the forums cant fullfill the students questions.

A little slower than the last ones, not my favorite but great use of hands-on projects and enagagement

Needs more depth. Instructors should reference more external readings since the lectures are brief.

The last assignment of Week 6 was far more advanced than the rest of the material.

You could focus more on Spark that is the widely software for Big data Processing

very nice, just wish the environment was using docker instead of virtual machines

I think that there should be more exercises for MongoDB and Spark assigments.

Good course. But we couldn't relate the theoretical videos with hands-on.

The final assessment somewhat not really well designed, imho.

The course and presentations were very informational and good. I enjoyed that aspect. I would have rated the course 4-5 star based on that. The reason for the low rating was the 6th module, and the fact that I felt very ill prepared for the syntax of creating all the operations in Spark (building out the Jupiter notebook). We really did not cover much of that, and it was quite punishing to search the web and sources to make things work. Even the instructions to export the csv file were misleading at best. I have a full time job and a family, I am not some young undergraduate with copious amounts of time to waste. While I am not opposed to some searching of other sources, I would like to have more of the useful information taught so that it is not so much of a burden. I believe that if you are going to test people on something, you should at least cover it in some sense.

With deep regrets I feel obliged to share a negative rating on the course. While the course material/video lectures are average to good (no rocket science but well done introduction into the subjects), the hands-on exercises and particularly the technical environment, i.e. Cloudera VM is entirely messed-up: - setup scripts are not working/ are outdated (e.g., anaconda requires no-check-certificate); user permissions are all set wrong and need to be corrected; firefox outdated with update function not working; countless error around spark context (SC) variables.... and so on... For a course that is so prominently promoted on the platform the least expectation is that the provided environment works and that students don´t need to spend hours on google to figure out how to debug the cloudera image.... Here, imo, a much better job can be done!

Although the contents of the course is good, I found that the hands-on exercises needed to pass tests were problematic due to many errors occurring when trying to setup the tools or running provided scripts. This means most of the limited time I have for this was spend browsing the course forums and the internet chasing solutions for errors occurring in the exercises and not on actually working on the assignments.

Also the course makes you install several tools/apps. In itself it is good to be exposed to these tools, however some of these are only used to a limited extent, while still taking time to install and setup. Worst is one of the tools requiring personal information in order to be downloaded and as a consequence being chased by sales reps for the tool.

Again I'm torn between quitting this specialization and biting through the rest of it. While the course is good on the high-level view, the link to the low level, the tools and their application just doesn't work well for me. The different tools are presented and used just enough to scrape a tiny lttle bit of the surface, then you're heading on the next chapter. Like in the previous courses, the tools in the VM sometimes need quite a bit on tinkering until everything works as expected. The main drawdown in this course was the final test that I did not felt prepared for at all. On the bright side, you learn to love the Spark manual...

PLEASE, UPDATE THIS COURSE AND BRING IT TO TODAYS LEVEL. IT'S ACTUALLY BETTER THAN THE AVERAGE FEELING IT LEAVES BEHIND.
