Pierre Beauvois commented on KNOX-1033:
---------------------------------------

I'm currently working on a first version. I'm facing issues on this one and more particularly
with the REST call to timeline's REST API. AS a result, I can't get any jobs and the UI returns
an error. Any help would be appreciated.

Tez topology:

NB: I'm testing the service with Tez 0.8.4.
