I just came across your postings, as I was looking for some information about setting up a Hadoop cluster on Docker.
I heartly agree with you, that Docker adds no (measurable) overhead to the execution.
The thing, I am wondering about, which is the filesystem in Docker that you are using? I am guessing it is not AUT.
Do you have any comparessing data for the Docker filesystems under the heavy load of Hadoop and its eco-system?
It would be great, if you could give me some hints or directions.
Thank you very much in advance.
