Subject [jira] Commented: (HADOOP-5670) Hadoop configurations should be read from a distributed system
Date Wed, 15 Apr 2009 21:43:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699408#action_12699408
] 

Todd Lipcon commented on HADOOP-5670:
-------------------------------------

Another nice thing about this is that you can use DNS for a super-simple HA/metaconfig system.
Simply point all the hadoop nodes at http://confmaster/config, then set up CNAME or A records
on the local domain network to the right machines. If one confmaster is down, it'll just pull
from another.

> Rather than distributing the hadoop configuration files to every data node, compute node,
etc, Hadoop should be able to read configuration information (dynamically!) from LDAP, ZooKeeper,
whatever.
