Despite its name, the conf/masters file defines on which machines Hadoop
will start secondary NameNodes in multi-node cluster. In some case, this is
just the master machine. The primary NameNode and the JobTracker will
always be the machines on which you run the bin/start-dfs.sh and
bin/start-mapre
My understanding is that conf/masters is used only by the bin/ or sbin/
scripts - like start-*.sh, while the conf property is used by the Hadoop
daemons running on that particular node.
Hope that helps,
