[jira] Created: (MAPREDUCE-1466) FileInputFormat should save #input-files in JobConf

FileInputFormat should save #input-files in JobConf
---------------------------------------------------

                 Key: MAPREDUCE-1466
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1466
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: client
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy
            Priority: Minor
             Fix For: 0.22.0


We already track the amount of data consumed by MR applications (MAP_INPUT_BYTES), alongwith, it would be useful to #input-files from the client-side for analysis. Along the lines of MAPREDUCE-1403, it would be easy to stick in the JobConf during job-submission.
