[slurm-users] Disabling --nodelist

[Aaron Jackson]

Thanks both who helped with this. I had to recompile Slurm with Lua, but
I now have it working.

function slurm_job_submit(job_desc, part_list, submit_uid)
    if not (job_desc.req_nodes == nil) then
      slurm.log_user("Must not specify nodelist")
      return slurm.FAILURE
    end

    return slurm.SUCCESS
end

The documentation for this API was a bit lacking, ended up having to
read the C source. Is SchedMD accepting pull requests for documentation?
I'd be happy to assist here.

Thanks!

Aaron
