Subject [jira] [Commented] (FALCON-369) Refactor workflow builder
Date Tue, 03 Jun 2014 09:56:02 GMT

Satish Mittal commented on FALCON-369:
--------------------------------------

In the class diagram, FeedRetentionBundleBuilder in bottom right is mentioned thrice. Am assuming
it is a typo for FeedRetention/FeedReplication/Process bundle builders, right?

> 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
