Shwetha G S commented on FALCON-369:
------------------------------------

[~svenkat], thanks for your feedback. Attached is the class diagram for the workflow builder.
It separates out different lifecycles(with respect to oozie entities), however doesn't add
lifecycle as separate entity. Adding lifecycle can be discussed and addressed as part of another
jira. It will be one to one mapping to oozie entities. 

Its a big patch and I will not be able to rebase with new commits. I need this refactoring
for adding dry run feature. Can you please take a look at the earliest? Thanks

> Currently, feed/process workflow builder is a single class which handles all different
cases of lifecycles, storage types, workflow engines and building all oozie entities(workflow,
coord and bundle). This is not readable and difficult to maintain. This needs some re-factoring.
> Approach:
> Maintain different builders for
> 1. oozie entities - workflow, coord and bundle. 
> 2. entity types - feed and process
> 3. lifecycle - process, retention and replication
> 4. workflow engines - oozie, pig and hive
