Jing Zhao updated MAPREDUCE-6248:
---------------------------------
Attachment: MAPREDUCE-6248.001.patch
Thanks for the review, Vinod! Update the patch to address your comments. Now
DistCp keeps its constructor, {{run}} (overriding {{Tool}}), and {{execute}}
(which has been called by downstream applications) as public. Also two
additional public methods are added: {{createAndSubmitJob}} and
{{waitForJobCompletion}}.
> Allow users to get the MR job information for distcp

>
> 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.
