Function Details

Get the master node and my own hostname.

This can be either used for a 'soft' check (compared to CheckMaster, which exits) or just for computing both at the same time.

The function does not handle any errors, these should be handled in the caller (errors.ConfigurationError, errors.ResolverError).

Parameters:

Returns: tuple

a tuple (master node name, my own name)

Checks the node setup.

If this is the master, the function will return. Otherwise it will exit with an exit code based on the node status.
