Masters and Slaves in Slaves machines
Regards for all!
I'm configuring a HDFS with multi-nodes, I've some problems with slaves
machines, specifically configuring these archives:
masters
slaves
hadoop-site.xml
I don't have idea which ip address I should have to write in "masters"
archive in slaves machines...
localhost or "my master machine".
And so, with others archives.
Thanks for ur help,

In masters file, you should write your master's address.
In slaves file, you should write all of your slaves' addresses, seperated by
'\n' (newline char)

1. config the namenode and jobtracker node in hadoop-site.xml :
<property>
<name>fs.default.name</name>
<value>your-name-node:9527</value>
</property>
<property>
<name>mapred.job.tracker</name>
<value>your-job-tracker-node :9528</value>
</property>
2. config all the datanode and tasktracker node by the "slaves" file,
node1
node2
node3
....
3."masters" is for secondary namenode,so if you just want to run the hadoop
,my suggestion is remove the content and
leave it as an empty file.

your master machine in your masters file
slaves file is no neccessary in slaves machines,because slave machine
doesn't talk to each other, it just talk to master
