Ravi Prakash created MAPREDUCE-4645:
---------------------------------------

             Summary: Providing a random seed to Slive should make the sequence of filenames completely deterministic
                 Key: MAPREDUCE-4645
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4645
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: performance, test
    Affects Versions: 2.0.0-alpha, 0.23.1
            Reporter: Ravi Prakash
            Assignee: Ravi Prakash


Using the -random seed option still doesn't produce a deterministic sequence of filenames. Hence there's no way to replicate the performance test. If I'm providing a seed, its obvious that I want the test to be reproducible.
