There's no specific doc for setting up users on the gateway nodes.
Depending on if you have kerberos security enabled or not, there are a
few places that users may need to get created.
If there is no kerberos, you either need to create the users as local
users on the gateway nodes, name node, and job tracker or you can use
a central user repository (typically LDAP) so you can manage the
If you have kerberos enabled, you also need to make sure that you
create a kerberos principal for each user and that the unix accounts
exist on all nodes in the cluster. Again, it's much easier if you use
something like LDAP to centrally manage the accounts.
If you want to set up your own LDAP, I'd recommend taking a look at
either OpenLDAP or Apache Directory.
