[jira] Commented: (WHIRR-246) Single place to store/load cluster state

["Andrei Savu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WHIRR-246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13002501#comment-13002501 ] 

Andrei Savu commented on WHIRR-246:
-----------------------------------

I like the idea of moving the logic for state persistence in a single place. How about storing this info outside the local machine by using the BlobStore API and displaying it as output for ./bin/whirr list-cluster? Should we rename ClusterStore to ClusterState? (more self-explanatory to me)

> Right now cluster state is written and read from the ~/.whirr/cluster-name/instances file and logic to write and update it is spread between the Service and DestroyInstanceCommand (that I know of).
> Since for WHIRR-214 the file must be updated (in another class) and for WHIRR-238 an altogether different method of storing cluster state will be required I think it might be time to move the read/write state logic to its own file (or factory in the future).
> I'll attach a very preliminary patch just to get some feedback.
