Notice the number of entries in the {{actions}} in each output. When
{{len=2}}, it was 2; when {{len=1}} it was 1; and when {{len=0}} it was 2
again.

> If you fetch a URL such as:
> {noformat}
> http://localhost:11000/oozie/v1/job/0000002-130731172618471-oozie-oozi-C?len=1
> {noformat}
> you'll get the job info for the coordinator job, and 1 of its actions.
> If you only want to get the info for the coordinator job itself and don't
> care about the actions, it seems logical that {{len=0}} should do this;
> however, it seems to be ignored and gives you all actions instead.
