Virag Kothari updated OOZIE-1234:
---------------------------------
Attachment: jms_notification_spec.docx
The attached jms notification spec shows the type of information available in
part of JMS payload and JMS header. The message selector can be applied to JMS
header and is used to filter messages on the JMS server. If the message
satisfies the selector criteria, it will be delivered to the consumer and the
JMS payload can be inspected.
> JMS Event Listeners for publishing notifications related to workflow and
> coordinator

>
> The event listeners will emit notifications for workflow, coordinator and SLA
> events. There are different ways of sending notifications like through JMS or
> email.
> This JIRA will focus on JMS Event listeners for workflow and coordinator
> related events.
> JMS implementation of event listener will send messages on a particular topic
> In addition to the JMS payload, the notification message will have properties
> on which the consumers can apply selectors to filter messages at JMS server.
> The JMS event message will be serialized and Oozie will also provide a helper
> class for consumers to deserialize these messages back to Java Objects.
> Classes
> EventMessage: There can be different event messages like
> WorkflowJobSuccessMessage, WorkflowJobFailureMessage similar to different
> events in OOZIE-1209
> EventListener: Listener to publish event messages on msg bus. One
> implementation will be JMSWorkflowEventlistener for publishing workflow
> related event messages
> MessageFactory: Factory for providing serializer, deserializer and creating
> Oozie event messages instances
> MessageSerializer: Serialize the JMS messages. One implementation can be
> JSONMessageSerializer to send the messages as JSON string.
> MessageDeserializer: Class to convert the serialized string back to Java
> Event Messages.
