I am interested in the CCAH training being offered by Cloudera in a class, I have a question regarding the cluster set up for the practical session , do all the students in the class set up their individual cluster on EC2 or they all use the same EC2 cluster .
I believe that the instructor actually creates the instances and the students configure them as they go through the lab exercises. There are no documents about the set up, as far as I know.
I am on the certification side, so I'm not very familiar with the course. I've sent a request to an instructor, so hopefully there will be some additional details added to this post later.
Hi all, students who take Cloudera's Administrator course 
each get a set of (5) Amazon EC2 instances to use as their
own cluster of servers during the course.
The instances are of type size t2.medium which provides 4GB of
RAM and 2 vCPUs for each instance.
During the class, students can use a "fast forward" script
to catch up to a particular exercise (or, "rewind" to a previous exercise).
The "fast forward" script uses Cloudera Manager's own API to
install and setup the services that are taught during the class.
After the class, we provide detailed instructions for setting
up your own cluster of the exact same AMIs to be able to
reproduce the exact exercises (and "fast forward" scripts)
from the class.
The AMI instances that are provided as part of the class
are free during the duration of the class, but students will
need an Amazon EC2 account to reproduce the AMIs after
the class ends.
Thanks, and please feel free to ask more questions about the
course on this thread.
