Vinod Kumar Vavilapalli commented on MAPREDUCE-6248:
----------------------------------------------------

Why not have a public API in DistCp and use that programmatically instead of persisting IDs into files and then reading them?

> 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.
