The file masters in the hadoop default installation contains localhost
because in this default installation hadoop work in local mode in one
node
localhost in master's file mean that the namenode and the jobtracker
wil run on the local node

Thank you very much for reply.
Is there any reason masters file contains localhost in default installation
of hadoop?

Datanodes don’t connect to the secondary namenode, and slaves file should
contain the hostnames where you want to start the datanode. It can be
localhost.

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.
