Agreed. It would still be necessary to support local configuration
for single-node clusters and testing though. The configuration should
be able to take its values either from a distributed system, or from
local values. ZooKeeper would be a reasonable system for retrieving/
setting the key-value pairs of the configuration file.

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.
