Kashif Hussain, If you are working on the same job and the next three schedules are just for recovery, you can schedule it once a day by setting retry options in workflow. User-retry for workflow actions are available since Oozie 3.1 with the following syntax.
<workflow-app xmlns="uri:oozie:workflow:0.3" name="wf-name"> <action name="a" retry-max="2" retry-interval="1"> </action> - Goun 2017-04-09 14:31 GMT+09:00 Per Ullberg <[email protected]>: > I think we use all three approaches in different workflows. :) > > Pick whatever works for you.
