submitAndMonitorJob() doesn't play nice with MultipleOutputFile
---------------------------------------------------------------

                 Key: MAPREDUCE-2715
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2715
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Geoffrey Young


part of submitAndMonitorJob() balks if the output directory currently exists but is non-empty:

  "Error launching job , Output path already exists : "

this logic actually conflicts with the ideas behind MultipleOutputFile, where the output file
path is calculated later on.

it would be really nice to remove the restriction for non-empty output directories in submitAndMonitorJob()
so that MultipleOutputFile becomes more useful - as it stands now, I can't, for example, specify
a base output path then use MutlipleOutputFile to partition by date on a daily basis.

thanks.
