datanode configuration and slave file

Hi:

   To configure multiple data nodes, would I add to
hadoop-default.xml or
the slave file or both?

Thanks

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.
