Subject [jira] [Commented] (HDFS-12010) TestCopyPreserveFlag fails consistently because of mismatch in access time
Date Thu, 22 Jun 2017 06:18:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16058816#comment-16058816
] 

Mukul Kumar Singh commented on HDFS-12010:
------------------------------------------

The cause of this bug are following lines

{code}
    fs.setTimes(FROM, MODIFICATION_TIME, ACCESS_TIME);
    fs.setPermission(FROM, PERMISSIONS);
    fs.setTimes(DIR_FROM, MODIFICATION_TIME, ACCESS_TIME);
    fs.setPermission(DIR_FROM, PERMISSIONS);
{code}

Setting permissions after setting the access and modification time will reset these times,
Hence these events needs to be re-ordered.
