Robert Kanter updated OOZIE-2644:
---------------------------------
Description:
When you use the
[Workflow|https://oozie.apache.org/docs/4.2.0/WorkflowFunctionalSpec.html#a5_Workflow_Notifications]
or
[Coordinator|https://oozie.apache.org/docs/4.2.0/CoordinatorFunctionalSpec.html#a15._Coordinator_Notifications]
Notification features, Oozie can end up queuing up a lot of
{{WorkflowNotificationXCommand}} and {{CoordActionNotificationXCommand}}. This
happens even if there's no notification configured on the job (which I imagine
is most of the time); in this case, the {{execute}} method simply does nothing.
This is wasteful and clogs the queue up.
We should change the code so that it doesn't queue up one of these Commands
unless there's actually a URL to notify.

It would also be nice if we could combine the code more between the two, but
that might be tricky because of the parenting.
