Subject RE: Overlapping DFS clusters
Date Wed, 25 Oct 2006 18:16:27 GMT
You really want a backup namenode for the dfs, which is not supported at
this time.

Multiple overlapping dfs clusters are possible, but they'll be totally
independent, and must be configured with different locations for data, temp
data etc. - not what you want.
