[jira] Created: (MAPREDUCE-1788) o.a.h.mapreduce.Job shouldn't make a copy of the JobConf

o.a.h.mapreduce.Job shouldn't make a copy of the JobConf
--------------------------------------------------------

                 Key: MAPREDUCE-1788
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1788
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client
    Affects Versions: 0.21.0
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy
            Priority: Blocker


Having o.a.h.mapreduce.Job make a copy of the passed in JobConf has several issues: any modifications done by various pieces such as InputSplit etc. are not reflected back and causes issues for frameworks built on top.
