Hi All, I am currently testing slurm version 19.05.3-2 on Centos 7 with one master and 3 nodes configuration. I used the same configuration that works on version 17.02.7 but for some reasons, it does not work on 19.05.3-2.
$ srun hostname srun: error: Unable to create step for job 19: Error generating job credential srun: Force Terminated job 19 If i run it as root, it works fine. $ sudo srun hostname piglet-18
