Subject [jira] [Commented] (HDFS-2231) Configuration changes for HA namenode
Date Mon, 08 Aug 2011 21:30:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081207#comment-13081207
] 

Todd Lipcon commented on HDFS-2231:
-----------------------------------

Sure, I agree logical names are preferable. But having an automatic mapping so you can deploy
the same hdfs-site.xml to all nodes is better for manageability.

I used to manage some MySQL active-active setups and it was always a pain to deal with changing
server_id on the local config of either side of the [otherwise-identical] pair.
