Allow retrieval of instance roles
---------------------------------
Key: WHIRR-150
URL: https://issues.apache.org/jira/browse/WHIRR-150
Project: Whirr
Issue Type: Improvement
Components: core
Reporter: Tom White
After a cluster has been launched there is no way to access the roles running
on particular instances. It would be useful to find the workers in a Hadoop
cluster, so you could operate on them (e.g. restarting the daemons on them).
How this is implemented is probably different for different clouds. E.g. on EC2
it could be accomplished using tags, on other platforms a local file might be
sufficient, and a blobstore might be another way.
