Code review comment for lp:~hazmat/charms/precise/hadoop/trunk

I'm strongly opposed to changes that break backwards compatibility. However, I'm letting this one go through, since you'd need juju < 0.7 to successfully deploy and change config for this charm - given that these releases are all depreciated it's recommended people move forward. Since you can't change config options for this charm in juju-core anyone upgrading won't be affected.

That being said, I'd like to state that all updates to charms must maintain backwards compatibility. Shortcomings, bugs, and differences between "pyjuju" and "gojuju" shouldn't be addressed by changing (and breaking) charms.
