Subject [jira] [Commented] (FALCON-141) Support cluster updates
Date Fri, 05 Feb 2016 15:24:39 GMT

    [ https://issues.apache.org/jira/browse/FALCON-141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15134317#comment-15134317

Balu Vellanki commented on FALCON-141:
--------------------------------------

[~sriksun] : [~venkatnrangan] and I had a discussion about this and we propose the following
solution. 

1) Maintain a cluster version per cluster entity, this information is transparent to the user.

2) There are clusters associated with every feed and process.  Falcon should maintain a cluster
version associated with everyFeed/Process Cluster. 
3) Update the feed/process bundle/coordinator in the workflow engine during one of the following
scenarios. 
    a) Falcon is started in normal mode  OR
    b) A user makes a touch API call on entity.

This way, instead of having an opaque flag, Falcon will have a specific reason while updating
dependent feed/process entities.
