Tom White updated WHIRR-150:
----------------------------
Attachment: WHIRR-150.patch
Here's a patch which writes the instances file for all clusters. This is done
by Service, not LaunchClusterCommand, since it is not particularly CLI-specific.
I had to move DnsUtil to core since its a dependency, so I moved DnsUtilTest to
core's integration directory (part of WHIRR-162).
> Allow retrieval of instance roles

> 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.
