The job has state "CG" which means "Completing".  The Completing status is 
explained in "man sinfo".

This means that Slurm is trying to cancel the job, but it hangs for some

What is your UnkillableStepTimeout parameter?  The default of 60 seconds 
can be changed in slurm.conf.  My cluster:

$ scontrol show config | grep UnkillableStepTimeout
UnkillableStepTimeout   = 126 sec

It may be impossible to kill the job's processes, for example, if a 
filesystem is hanging.

You may log in to the node and give the job's processes a "kill -9".  Or 
just reboot the node.
