Jakob Homan commented on HADOOP-5670:
-------------------------------------
Wrapping filesystem around ldap/zk/etc seems a bit heavy. Another option would
be to extend Configuration and create ZooKeeperConfiguration,
LDAPConfiguration, HTTPConfiguration, etc. Each node would still require a
small file to tell it where/which resource to locate. A builder could read
this file and construct the appropriate configuration and hand it off to the
node. This would be very pluggable and transparent to the nodes.
> Hadoop configurations should be read from a distributed system

> 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.
