             Summary: Fix FileTargetImplTest.testHandleOutputsMovesFilesToDestination instability
                 Key: CRUNCH-613
                 URL: https://issues.apache.org/jira/browse/CRUNCH-613
             Project: Crunch
          Issue Type: Bug
          Components: Core
            Reporter: Clément MATHIEU
            Assignee: Josh Wills


{{FileTargetImplTest.testHandleOutputsMovesFilesToDestination}} consistently fails on my machine
because it relies on the erroneous assumption that {{handleOutputs}} will preserve part indexes
in file names.

If you are lucky the {{part-m-00000}} file created by the MR job will be copied to the destination
folder with the exact same name. However it just... luck. Final index only depends on  iterator
order which can vary from machine to machine (OS, FS, JDK etc.)

This test should be rewritten to not rely on a such erroneous assumption.
