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.
