TestMiniMRWithDFSWithDistinctUsers is very broken
-------------------------------------------------
Key: MAPREDUCE-2445
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2445
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: security, test
Affects Versions: 0.22.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Fix For: 0.22.0
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.
