Allen Wittenauer commented on HADOOP-5670:
------------------------------------------
I wish I had pictures of the whiteboard talk Owen and I had around this feature.
One the big things I want people to keep in mind is that a client of the grid
needs a lot of this information too. [e.g., something like default block size]
There is also the issue of multiple JobTrackers per file system.
You can do lovely things with a hierarchy of configuration information.
