for communication with the job manager. Like jobmanager.rpc.address, this value
is only interpreted in setups where a single JobManager with static
name/address and port exists (simple standalone setups, or container setups
with dynamic service name resolution). This config option is not used in many
high-availability setups, when a leader-election service (like ZooKeeper) is
used to elect and discover the JobManager leader from potentially multiple
standby JobManagers.</td>
