Unexpected warn-related error message if jobs don't start on slurm cluster

New to Julia

I am using ClusterManagers.jl to launch jobs on the university cluster. This is what happens if jobs time out

julia> addprocs_slurm(100);
srun: job 1218466 queued and waiting for resources
Error launching Slurm job:
ERROR: UndefVarError: warn not defined

Not sure where the warn is used? It seems cluster.jl:418 is

Base.wait(t_launch)

and t_launch is defined as

t_launch = @async launch(manager, params, launched, launch_ntfy)

I am assuming that the async_launch is failing and raising a warning, but I’m not sure where it’s defined. A grep on the jl files in Distributed returns no result.

Which version of Julia are you using please?
In slurm.jl

if time() > t0 + 60 + np
warn(“dropping worker: file not created in $(60 + np) seconds”)
break
end

I think that should be @warn

This seems to fix the issue, now it’s a proper warning instead of an error. This is on julia 1.1
