Date Mon, 12 Mar 2018 18:46:02 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16395694#comment-16395694

Íñigo Goiri commented on HDFS-11399:

HADOOP-9427 is missing in 2.X.
I reverted those commits and I'll add a branch-2 patch using Shell.WINDOWS.

>                 URL: https://issues.apache.org/jira/browse/HDFS-11399
>             Project: Hadoop HDFS
>          Issue Type: Sub-task
>    Affects Versions: 3.0.0-alpha2
>            Reporter: Yiqun Lin
>            Assignee: Yiqun Lin
>            Priority: Major
>             Fix For: 3.1.0, 2.10.0, 2.9.1, 3.0.2, 3.2.0
>         Attachments: HDFS-11399.001.patch, HDFS-11399.002.patch
> Found many tests run failed in Windows due to using {{DataNodeTestUtils#injectDataDirFailure}}.
One of the failure test:
> {code}
> java.io.IOException: Failed to rename D:\work-project\hadoop\hadoop-hdfs-project\hadoop-hdfs\target\test\data\dfs\data\data2
to D:\work-project\hadoop\hadoop-hdfs-project\hadoop-hdfs\target\test\data\dfs\data\data2.origin.
> 	at org.apache.hadoop.hdfs.server.datanode.DataNodeTestUtils.injectDataDirFailure(DataNodeTestUtils.java:156)
> 	at org.apache.hadoop.hdfs.server.blockmanagement.TestBlockStatsMXBean.testStorageTypeStatsWhenStorageFailed(TestBlockStatsMXBean.java:176)
> {code}
> The root cause of this is that the test method uses {{DataNodeTestUtils#injectDataDirFailure}}
to injects disk failures but however missing the compare operation {{assumeNotWindows}}. Currently
{{DataNodeTestUtils#injectDataDirFailure}} is not supported in Windows then the test fails.
> It would be better to add {{assumeNotWindows}} into {{DataNodeTestUtils#injectDataDirFailure}}
in case we forget to add this in test methods.
