Roman Shaposhnik commented on BIGTOP-840:
-----------------------------------------
I think this one could be closed. We still need to refactor our Puppet code for
puppet3 and everything, but that's a different story (and a different JIRA).
> Refactor Bigtop puppet code for better integration with newer Puppet and Whirr

> Our current puppet code is now showing its age (after all it was originally
> developed to run on, gasp, Puppet 0.25!). It would be nice to re-factor it so
> we can take care of the following shortcomings:
> # namespace all of our code under bigtop and get rid of extra hadoop-
> prefixes. For example, zookeeper server class will be accessible as
> bigtop::zookeeper::server
> # as a consequence of doing #1 we will be consolidating all of our code
> into a single bigtop module. Now, this could be controversial at first, but
> lets face -- Bigtop is an integration platform so chance of somebody using
> our zookeeper module with Adobe's hadoop module to deploy a cluster are
> pretty low. Also, moving everything into a single module will make it way
> easier for us to register it at Puppet Forge (http://forge.puppetlabs.com/)
> and engage additional community that way
> # make all of our code based on parameterized classes and get rid of all
> the dynamic scope lookups (which is deprecated in Puppet 3.0 anyway) and
> global variable settings.
> # separate data from puppet code as descibed over here:
> https://puppetlabs.com/blog/the-problem-with-separating-data-from-puppet-code/
> # pursue the roles/profiles class paradigm
> http://www.craigdunn.org/2012/05/239/
> If this still sounds pretty opaque to you, I'll post some POC code over the
> weekend so you can take a closer look.
> Also, if you have any other Puppet concerns -- please jump right in -- now is
> a good time to do a bit of spring cleaning.
> Finally, given that we will be introducing a brand new module (bigtop) all of
> our existing Puppet code will remain in place at least till Bigtop 0.7.0. By
> that time if the new one works well, we can deprecate the old one.
