Subject [jira] [Created] (HDFS-11399) Many tests fails in Windows due to injecting disk failures
Date Thu, 09 Feb 2017 05:55:41 GMT
Yiqun Lin created HDFS-11399:

             Summary: Many tests fails in Windows due to injecting disk failures
                 Key: HDFS-11399
                 URL: https://issues.apache.org/jira/browse/HDFS-11399
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 3.0.0-alpha2
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin

Found many tests run failed in Windows due to using {{DataNodeTestUtils#injectDataDirFailure}}.
One of the failure test:
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)
The root cause of this is that the test method uses {{DataNodeTestUtils#injectDataDirFailure}}
to injects disk failures but however missing the compare operation {{assumeNotWindows}}.

It would be better to add {{assumeNotWindows}} into {{DataNodeTestUtils#injectDataDirFailure}}
in case we forget to add this in test methods.
