> 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
> Attachments: hadoop-22-dfs-dir.tgz, HDFS-4732.1.patch
>
>
> 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.
