Subject [jira] [Commented] (HADOOP-12476) TestDNS.testLookupWithoutHostsFallback failing
Date Wed, 14 Oct 2015 16:38:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14957236#comment-14957236
] 

Arpit Agarwal commented on HADOOP-12476:
----------------------------------------

I could not think of a practical alternative to reflection for this test case without significantly
refactoring {{DNS}}. It's dependencies on DNS lookups and networking are not well isolated
and make unit testing difficult.

However I am not sure why it fails at all. [~jojochuang], have you seen it fail outside of
Jenkins?
