Jakob Homan commented on HADOOP-5670:
-------------------------------------
Odd. I replied as a comment but jira didn't seem to pick it up...
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.
