Andrei Savu commented on WHIRR-150:
-----------------------------------
This file could be useful for all current services and future ones. Why only
for Hadoop? Is there any particular reason why this file is not generated in
the {{LaunchClusterCommand}} class after the cluster is started?
Unrelated: I also think that
{{HadoopNameNodeClusterActionHandler.getConfigDir}} should be a method in
{{ClusterSpec}}.
> 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.
