[jira] [Created] (HDFS-4732) TestDFSUpgradeFromImage fails on Windows due to failure to unpack old image tarball that contains hard links

Chris Nauroth created HDFS-4732:
-----------------------------------

             Summary: TestDFSUpgradeFromImage fails on Windows due to failure to unpack old image tarball that contains hard links
                 Key: HDFS-4732
                 URL: https://issues.apache.org/jira/browse/HDFS-4732
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
    Affects Versions: 3.0.0
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


On non-Windows, {{FileUtil#unTar}} is implemented using external Unix shell commands.  On Windows, {{FileUtil#unTar}} is implemented in Java using commons-compress.  {{TestDFSUpgradeFromImage}} uses a testing tarball image of an old HDFS layout version, hadoop-22-dfs-dir.tgz.  This file contains hard links.  It appears that commons-compress cannot handle the hard links correctly.  When it unpacks the file, each hard link ends up as a 0-length file.  This causes the test to fail during cluster startup, because the 0-length block files are considered corrupt.
