Subject Re: datanode configuration and slave file
Date Wed, 06 Dec 2006 19:25:08 GMT
slave file is used by hadoop scripts to execute datanode on the slave  
nodes. that is the only place, where you should specify new  
datanodes. namenode currently does not know in advance about the  
datanodes that are going to register.
