-------------------------------------

             Summary: TestTeraSort fails on Windows
                 Key: MAPREDUCE-6672
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6672
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: test
    Affects Versions: 3.0.0, 2.8.0
         Environment: OS: Windows Server 2012
JDK: Oracle 1.7.0_79
            Reporter: Tibor Kiss
            Assignee: Tibor Kiss
            Priority: Minor


TestTeraSort testcase fails on Windows.

The test case uses the build directory as test working directory.
Under Windows the build directory starts with a drive definition (C:),
which is interpreted as (an invalid) URI scheme. 

The fix is trivial: Add URI scheme to the beginning of the working directory.
