Thanks for the clarification.  I like the toast example. ;)

    Hi Rob,
    
    I don't think an epic is necessarily required. Cases where the changes are 
complex or could destabilize the trunk but don't span more than a few JIRAs 
probably don't need an Epic. For example, I see you've been working on adding 
Kerberos authentication to Ambari (awesome!) ... In this case, you might not 
have needed an epic if the work was only going to span a few different JIRAs. 
Since it did deal with logging into Ambari, a mistake here could render Ambari 
unusable, so its good to make your changes in a feature branch to test.
    
    With that said, using an epic to track and group child JIRAs certainly 
helps with the organization. In the case where you have an epic, yes, you are 
correct. The child JIRAs would be the commits you see on the feature branch. 
And when you successfully merge back into trunk, you can close the epic. 
    
    For example, let's say you had an Epic where Ambari needs to make toast. 
You'd have this in JIRA:
    
    AMBARI-1 - Implement Toast Making
      AMBARI-2 - Slice Bread
      AMBARI-3 - Buy Toaster
      AMBARI-4 - Magic
      AMBARI-5 - Unit Tests for Making Toast
    
    You feature branch would be called branch-feature-AMBARI-1 and would 
contain these commits:
      AMBARI-2 - Slice Bread
      AMBARI-3 - Buy Toaster
      AMBARI-4 - Magic
      AMBARI-5 - Unit Tests for Making Toast
    
    When you merge back in, each child JIRA appears on trunk. The master Epic, 
AMBARI-1, does not, and can now be resolved.

related to child JIRAs of that Epic.  Would this be a good approach to take, or 
would the additional Epic create too much unnecessary overhead?
