usermapping - user mapping entry file format
A usermapping entry is used to define alias names for a cluster user.
The user's name known by the scheduling system is known as the cluster
user. If the cluster user doesn't match the user account name on an
execution host, the usermapping feature can solve the problem.
Each line in the usermapping entry file specifies a user name and the
host(s) where he has an account.
A list of currently configured user mapping entries can be displayed
via the qconf(1) -sumapl option. The contents of each enlisted user
mapping entry can be shown via the -sumap switch. The output follows
the usermapping format description. New user entries can be created and
existing can be modified via the -aumap, -mumap and -dumap options to

attribute might be overwritten for a certain hostgroups or single host.

will be peter1. hostgroup(5) to obtain for more information about
