I need to write multiple site.pp file for the same hosts. It gives me the following error 

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Node 'default' is already defined at line 2; cannot redefine at line 2 on node node-002.example.com

For example :

My first site.pp 

vi hosts-site.pp
default{
  }
 node "node-002.example.com" {
           ## Rules here to update /etc/hosts
         }

Next Site.pp with the same node but different operations .

 vi fstab-site.pp
default{
  }
 node "node-002.example.com" {
           ## Rules here to update /etc/fstab
         }

How to achieve the same. We need to write multiple operations for the same nodes for which we need to maintain different site.pp

Puppet is not supposed to have multiples site.pp

If your goal is to apply manually one of your configuration, you can use the --tags option. By the way, you should configure your agent to act as noop so it will not apply your changes when you don't want it.

So you could have a site.pp like this :

node "node-002.example.com" {
  class {'hosts_configuration'}
  class {'fstab_configuration'}
}

Where hosts_configuration and fstab_configuration are modules that configures what you want.

Then, when you want to apply hosts configuration, you could use on your node-002

puppet agent -t --tags=hosts_configuration

And it will apply the needed configuration for hosts.

If you really want to have multiples site.pp, you can do this using environments:
