Subject [jira] [Commented] (HADOOP-9449) TestTableMapping failing in some networks
Date Mon, 01 Apr 2013 21:35:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13619205#comment-13619205

Steve Loughran commented on HADOOP-9449:
----------------------------------------

I don't have a stack trace for this as it's been discarded -I wasn't expecting it to suddenly
start working again this evening. The laptop is the same, the source tree has not been updated
(I was working in yarn, not common).

This makes me wonder if there is some network problem -the test routine is calling {{InetAddress.getByName()}}
deep down in the resolve logic: what if the failing network is resolving the names/IP addresses
to "something", which is then mapping to {{/default-rack}}?

> {{TestTableMapping.testResolve()}} was failing for me, with the test racks resolving
to {{"/default-rack"}}. This is a test that worked last week, and, now I am home, works again.
Yet it was failing repeatedly today, while I was working remotely in London. Network related?
