             Summary: JMS in NotificationXCommand
                 Key: OOZIE-929
                 URL: https://issues.apache.org/jira/browse/OOZIE-929
             Project: Oozie
          Issue Type: New Feature
            Reporter: Britt Cyr
            Assignee: Britt Cyr


Currently for each notification, oozie uses an http connection to send a 
notification. Oozie could use a pub-sub model and a JMS message bus.

1. There are a few options for the topic. It could be user generated, although 
this would allow a lot of topics and inconsistent naming. It could be per job 
so users could subscribe to see the notifications of certain jobs. It could be 
done per user.

2. Ways to handle the large number of notifications since one notification 
could go to many subscribers. The payload of the notifications should be 
considered. Should it include everything about the action or should it only 
include important things like action id, action status, and time?
