Subject [jira] Commented: (HADOOP-5670) Hadoop configurations should be read from a distributed system
Date Thu, 16 Apr 2009 12:41:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699677#action_12699677
] 

Andrey Kuzmin commented on HADOOP-5670:
---------------------------------------

Couple of suggestions (assuming zookeeper option) based on past experience with similar issue.

1. Splitting configuration into two parts - default and site-specific overrides (with further
specialization down the line)  - would simplify hadoop upgrade by minimizing upgrade impact
on locally overridden options. 

2. If zookeeper does not provide for node-local persistent caching, adding this option specifically
for configuration data could support disconnected node operations if need be (say, for sanity
checks on start-up).

> 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.
