[jira] [Updated] (HDFS-3824) TestHftpDelegationToken fails intermittently with JDK7

Posted by "Trevor Robinson (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/HDFS-3824?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Trevor Robinson updated HDFS-3824:
----------------------------------

    Attachment: HDFS-3824.patch

The issue is caused by {{testHdfsDelegationToken}} expecting {{SecurityUtilTestHelper.setTokenServiceUseIp(true)}}, but the other tests end up setting it to false via {{checkTokenSelection}}.
