High level things to do:
- Help dcops to rack/setup/deploy the new hosts: two masters, one coordinator and three workers. This will likely need some partman config or similar.
- Come up with the the new config in puppet for the test cluster. I have gathered some things to keep in mind when bootstrapping a testing cluster https://wikitech.wikimedia.org/wiki/User:Elukey/Analytics/Hadoop
- Once all is done, decommission the old test cluster and give the green light to the DC ops team to decommission analytics1028->40.
- Special consideration for analytics1041 that runs our Druid testing cluster. We'll need to find a solution, maybe a co-location somewhere or possibly a VM (more likely). 1041 will need to be decommed as well.
See subtasks for more info :)
