[jira] [Created] (MAPREDUCE-6248) Persist DistCp job id in the staging directory

Jing Zhao created MAPREDUCE-6248:
------------------------------------

             Summary: Persist DistCp job id in the staging directory
                 Key: MAPREDUCE-6248
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6248
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: distcp
            Reporter: Jing Zhao
            Assignee: Jing Zhao


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.
