Review request for Falcon.

Bugs: FALCON-1495

Repository: falcon-git


Most of the times , when there are failures in the pipelines, retries run and the workflows
might have got succeeded in sub sequential retry. But for end user to figure out why it has
failed initially might be useful to understand for failures handling and SLA misses.

As of now to figure out the same, its a tedious task to get such information by either going
through oozie DB/logs or via the logs backed up in hdfs by the falcon postprocessing(which
is 100% reliable as in few cases, falcon post processing might fail or for some reason if
it couldn't back up the logs).

In either case, Falcon should abstract the oozie client layer to be used by end user, and
support all runs status to end user.
