> This test has a number of issues:
> - it side steps the normal job submission API for no apparent reason, manually writing
splits file and uploading submission files. (but forgets to upload the job jar, so the jobs
all fail)
> - it doesn't call waitForCompletion, or check job status (so it doesn't notice that the
jobs all fail)
> - it doesn't verify in any way that the job output is owned by the user who supposedly
ran the job
> - it shuts down DFS before MR
> These all conspire to make it pass, but it isn't actually testing anything.
