Subject [jira] [Commented] (HADOOP-9099) NetUtils.normalizeHostName fails on domains where UnknownHost resolves to an IP address
Date Tue, 27 Nov 2012 23:42:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9099?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13505062#comment-13505062
] 

Mostafa Elhemali commented on HADOOP-9099:
------------------------------------------

Personally I would've used something even more unlikely, such as "ThisIsNotARealHostName-ItJustCant",
but I guess UnknownHost123 is not very likely to exist :).

+1 (non-binding).
