             Summary: Improve Oozie action retry functionality documentation
                 Key: OOZIE-3020
                 URL: https://issues.apache.org/jira/browse/OOZIE-3020
             Project: Oozie
          Issue Type: Improvement
            Reporter: Peter Cseh


Oozie supports retry functionality and it is mentioned in the following 
documentation: 
https://oozie.apache.org/docs/4.2.0/WorkflowFunctionalSpec.html#a18_User-Retry_for_Workflow_Actions_since_Oozie_3.1
The current documentation mentions some config values, but does not explain 
them properly:

oozie.service.LiteWorkflowStoreService.user.retry.error.code.ext 
oozie.action.retry.interval
.......
Once the above is done, user needs to configure retry in the workflow action.
<action name="hello" retry-max="2" retry-interval="1">

It would be good to document this in a consolidated manner. What are the 
possible error codes? What is the unit of the retry-interval? etc.
