--------------------------------------------

             Summary: FalconException shouldn't be catched in AbstractRerunHandler in case
of obtaining Workflow engine from entity
                 Key: FALCON-1735
                 URL: https://issues.apache.org/jira/browse/FALCON-1735
             Project: Falcon
          Issue Type: Bug
            Reporter: pavan kumar kolamuri
            Assignee: pavan kumar kolamuri


WorkflowEngineFactory.getWorkflowEngine(Entity entity) throw FalconException in three cases

1) When it didnt find org.apache.falcon.workflow.engine.FalconWorkflowEngine this class in
class path
2) When StateStore is not initialized 
3) FalconException will be thrown if entity is not present in configStore. 

I thought when org.apache.falcon.workflow.engine.FalconWorkflowEngine doesn't exists its better
to return defaultworkflowengine but looks like it might not occur since FalconWorkflowEngine
will be present always from now .
Second case is not possible it won't throw FalconException it might throw other runtime exceptions

Third case won't occur generally but still we shouldn't catch exception and return Default
WorkflowEngine.
