-----------------------------------
Summary: TestDatanodeStartupFixesLegacyStorageIDs fails on Windows due to failure to unpack old image tarball that contains hard links
Key: HDFS-9138
URL: https://issues.apache.org/jira/browse/HDFS-9138
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Reporter: Chris Nauroth
Assignee: Chris Nauroth
Priority: Minor
{{TestDatanodeStartupFixesLegacyStorageIDs#testUpgradeFrom22via26FixesStorageIDs}} uses a checked-in DataNode data directory that contains hard links. The hard links cannot be handled correctly by the commons-compress library used in the Windows implementation of {{FileUtil#unTar}}. The result is that the unpacked block files have 0 length, the block files reported to the NameNode are invalid, and therefore the mini-cluster never gets enough good blocks reported to leave safe mode.
