masters/slaves files content

Hi,

In default installation hadoop masters and slaves files contain localhost.
Am I correct that masters file contains  list of SECONDARY namenodes?

If so, will localhost node try to start secondary namenode even if it
already have one?
More over will datanodes try to contact itself in order to try to reach
 secondary namenode on localhost?

should I keep localhost in slaves in case I want to run datanode on same
sever I start cluster and run namemode?

This is my first hadoop experience,
Thanks in advance.
