In oozie, input-events are pretty straightforward, if the specifies file/folder is not present, the coordinator job is kept in WAITING state. But I could not understand what output-events does.
As per my understanding, the files/folders specified in output-events tag should be created by oozie in case all specified actions are successful. But that does not happen. I cannot find any relevant logs either. Nor are the documentations clear about this.
So, the question is, does Oozie really create files/folders specified in output-events? Or does it just mention that these particular files/folders are created during the workflow and the responsibility of creation is on jobs, not on Oozie?

Always the actions generate the data, these settings are just for control. You'll find some examples here
