Subject [jira] Commented: (HADOOP-3988) The elephant should remember names, not numbers.
Date Thu, 13 Nov 2008 07:52:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12647215#action_12647215

Yossi Ittach commented on HADOOP-3988:

We are trying to do something similar - but instead of changing the DNS scheme , we're using
floating IP - So it should override all the caching. I'll update when I have more results.

so prevents the use of DNS CNAMEs for any sort of fail over capability.
