Subject Re: ec2 clusters launched at 9fe693b5b6 are broken (?)
Date Tue, 15 Jul 2014 05:32:16 GMT
Okie doke--added myself as a watcher on that issue.

On a related note, what are the thoughts on automatically spinning up/down
EC2 clusters and running tests against them? It would probably be way too
cumbersome to do that for every build, but perhaps on some schedule it
could help validate that we are still deploying EC2 clusters correctly.

Would something like that be valuable?
