Niels Basjes commented on HADOOP-11843:
---------------------------------------

- docker version: I think the easiest and most portable sanity check for the 
right docker version is to check if you become root when inside the container.
Good to hear we are getting close to having the right set of tools.
- jdk: How can I automate the download of the Oracle JDK ? Last time I did that 
you needed to accept the licence and then there was a (unique looking) download 
url. I propose to stick to the openjdk, perhaps with some additional settings. 
What was the memory setting you used for the boot2docker vm? I can check for 
available memory when entering the container and warn if it is too low.
- python: What I understand is that it is I should install python 2.7 and 
create an alias/symlink so you can simply run 'python'. Should python 3 be 
uninstalled?

> ( As discussed with [~aw] )
> In AVRO-1537 a docker based solution was created to setup all the tools for 
> doing a full build. This enables much easier reproduction of any issues and 
> getting up and running for new developers.
> This issue is to 'copy/port' that setup into the hadoop project in 
> preparation for the bug squash.
