Subject [jira] Commented: (HADOOP-5670) Hadoop configurations should be read from a distributed system
Date Thu, 16 Apr 2009 03:18:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699506#action_12699506
] 

Mahadev konar commented on HADOOP-5670:
---------------------------------------

making a case for zookeeper :), to write a configuration layer on top of zookeeper would be
just 20-30 lines of code and we can handle around >20K writes per second (with 3 servers,
which I dont think would be necessary but other apps also could use zookeeper) and >50K
reads/sec. Also zookeeper has a pretty strong HA story.

> 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.
