Jing Zhao updated MAPREDUCE-6248:
---------------------------------
    Attachment: MAPREDUCE-6248.000.patch

Patch implementing [~vinodkv]'s proposal. The patch simply adds a new public {{createAndSubmitJob}} method which returns the mapreduce job object.

> Currently the DistCp is acting as a tool and the corresponding MapReduce Job  is created and used inside of its {{execute}} method. It is thus difficult for external services to query its progress and counters. It may be helpful to persist the job id into a file inside its staging directory.
