Balu Vellanki updated FALCON-1442:
----------------------------------
Fix Version/s: 0.8
> Contract of WorkflowEngine API broken
> -------------------------------------
>
> Key: FALCON-1442
> URL: https://issues.apache.org/jira/browse/FALCON-1442
> Project: Falcon
> Issue Type: Bug
> Reporter: Pallavi Rao
> Assignee: Balu Vellanki
> Fix For: 0.8
>
>
> The bug is related to patch for FALCON-1371. Sorry to rake this up after the
> patch has been committed. I completely missed a problem when I reviewed the
> patch. My bad. The patch introduces 4-5 methods such as the one below:
> {code}
> public abstract boolean isActive(Map<String, BundleJob> bundles) throws
> FalconException;
> {code}
> This totally breaks the contract of the WorkflowEngine. The Workflow Engine
> API is not supposed to expose the internal details (whether the entity is
> submitted as bundle or not). The worflow engine API should accept only
> entities known to Falcon (such as cluster, entity, lifecycle).
> The new methods cause problem with the native scheduler (which extends
> AbsractWorkflowEngine) as the native scheduler does not work with bundles.
> I understand that the reason it was introduced was to optimize the number of
> calls, but, I would rather have the cleaner separation :-)
