             Summary: consolidate get coord actions in OozieWorkflowEngine
                 Key: FALCON-991
                 URL: https://issues.apache.org/jira/browse/FALCON-991
             Project: Falcon
          Issue Type: Improvement
            Reporter: Shwetha G S
            Assignee: Ajay Yadava


OozieWorkflowEngine.getCoordActions() gets instances by calling 
oozieclient.getCoordAction() for each action. Its not efficient to call oozie 
API for each instance. Instead, doSummaryJobAction() gets all instances in bulk 
using oozieclient.getCoordJobInfo(). But this uses offset which won't work with 
purging of coord actions. A new API was added in oozie to get coord actions 
between timestamps. We should use that for both usecases
