Subject [jira] [Commented] (FALCON-1926) Filter out effectively non-falcon related JMS messages from Oozie
Date Mon, 25 Apr 2016 04:44:12 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1926?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15255883#comment-15255883
] 

Pallavi Rao commented on FALCON-1926:
-------------------------------------

The JMS broker selector can be applied on JMS message headers only and not body. Since we
don't set any particular message headers for the message sent in post processing action, we
will not be able to apply the selector, as long as we support sending messages in post-processing
action.

Two options:
1. Deprecate and remove messages being sent from post-processing action and apply selectors.
2. Add some headers for messages sent from post-processing action, so we can apply selectors.

Prefer option 1. There is already an option to turn-off messages from post-processing in startup.properties.

> Enabling Oozie JMS will flood the falcon JMS topic with both falcon and non-falcon submitted
workflow status notifications, where as Falcon is only interested in the messages for the
workflows it submitted. 
> Using JMS selector, only relevant messages need to be retrieved and processed further.
