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

    [ https://issues.apache.org/jira/browse/WHIRR-370?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13238563#comment-13238563 ] 

Andrei Savu commented on WHIRR-370:
-----------------------------------

Can we change the logging settings for Velocity? I see two news files created after running the unit tests: services/chef/velocity.log and services/hadoop/velocity.log. Overall I'm +1 for committing this change.

> Service configuration is currently done via the Whirr properties file by using a special per-service prefix (e.g. 'hadoop-common'). Using a templating approach (using e.g. Velocity) would make changing properties more familiar to users, and would make it easier for service implementors (since they wouldn't need to implement a generator class for each configuration file).
> It might even be possible to support the old syntax (so users can still configure everything from one file if they wished) by, e.g., appending all properties starting 'hadoop-common' to the core-site.xml template, etc.
