Subject [jira] [Commented] (HADOOP-7499) Add method for doing a sanity check on hostnames in NetUtils
Date Tue, 02 Aug 2011 22:52:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7499?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13078484#comment-13078484
] 

Jeffrey Naisbitt commented on HADOOP-7499:
------------------------------------------

According to the java.net.URI javadocs, "No lookup of the host, if any, is performed..." 
That is the main reason I chose java.net.URI over java.net.URL (even though there are definitely
other reasons too).
