Review request for Falcon.


Bugs: FALCON-1495
    https://issues.apache.org/jira/browse/FALCON-1495


Repository: falcon-git


Description
-------

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.
