Description Matt Mix 2020-09-09 13:18:53 MDT 
When inside a salloc session, with SLURM_CONF set, trying to use srun stats a socket and then fails to read the config.

srun: error: ClusterName needs to be specified
srun: fatal: Unable to process configuration file

Matt,

You're very likely hitting the same issue as in Bug 9704.

I'll just quote my reply from there (Bug 9704 comment 3):
>I can reproduce the issue and I have a patch that I'm passing to our QA queue.

>REQUEST_CONFIG RPC to download the configuration before doing its job.

Let me know if you want to try the patch before its QA is completed.

cheers,
Marcin
