Thanks Renfro. My scheduling policy is below.

“The SchedulerType configuration parameter specifies the scheduler plugin to
use. Options are sched/backfill, which performs backfill scheduling, and
sched/builtin, which attempts to schedule jobs in a strict priority order
within each partition/queue.”
