Refactor JobTracker.submitJob to not lock the JobTracker during the HDFS accesses
---------------------------------------------------------------------------------

                 Key: MAPREDUCE-1354
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1354
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Devaraj Das


It'd be nice to have the JobTracker object not be locked while accessing the HDFS for reading
the jobconf file and while writing the jobinfo file in the submitJob method. We should see
if we can avoid taking the lock altogether.
