[jira] [Created] (MAPREDUCE-5555) distcp should infer optimal number of mappers

Rob Weltman created MAPREDUCE-5555:
--------------------------------------

             Summary: distcp should infer optimal number of mappers
                 Key: MAPREDUCE-5555
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5555
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: distcp
            Reporter: Rob Weltman


Rather than requiring the user to calculate and provide an optimal number of mappers with the -m option, distcp should (if the option is not provided) be able to estimate a reasonable number.
