Subject [jira] [Commented] (YARN-2374) YARN trunk build failing TestDistributedShell.testDSShell
Date Thu, 31 Jul 2014 12:41:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-2374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14080805#comment-14080805
] 

Varun Vasudev commented on YARN-2374:
-------------------------------------

>From Jenkins:
{noformat}
TestDistributedShell.testDSShell:193 Expected host name to start with 'asf905.gq1.ygridcore.net/67.195.81.149',
was 'asf905/67.195.81.149'. Expected rpc port to be '-1', was '-1'.
{noformat}

It looks like the calls to NetUtils.getHostName() can return a short name or a fully qualified
domain name. I'm not sure how to resolve this. The test code and the code in distributed shell
app master call NetUtils.getHostName() and are getting different results. One solution could
be to modify both the distributed shell app master and the test to use fully qualified domain
names, but I'm open to suggestions.
