The course is ok but I found that there were some technical quirks that could be ironed out first. Example is to download the text files in the final assignment the command wget is invaluable. How to leave safe mode if the Name node is in safe mode. VirtualBox is default to 32 bit/ubuntu when the image is 64 bit/Centos/Redhat.In addition the course content is a bit little. It says 3 weeks but I finish it in 2 days. Perhaps it is about quality and not quantity.
