Subject [jira] [Created] (HADOOP-12603) TestSymlinkLocalFSFileContext#testSetTimesSymlinkToDir occasionally fail
Date Wed, 25 Nov 2015 22:33:11 GMT
Wei-Chiu Chuang created HADOOP-12603:
----------------------------------------

             Summary: TestSymlinkLocalFSFileContext#testSetTimesSymlinkToDir occasionally
fail
                 Key: HADOOP-12603
                 URL: https://issues.apache.org/jira/browse/HADOOP-12603
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Wei-Chiu Chuang


I have observed this test failure a few times in the past. When it fails, the expected access
time (of the file link) is always 1000 less than the actual access time.
