HA setting for per-job YARN session

i am using  the " per-job YARN session " mode deploy flink job on yarn.
The document
 says that "we don’t run multiple JobManager (ApplicationMaster)
instances" but still give an example about how to config an Highly
Available YARN Session cluster.

My question is:  does the " per-job YARN session "  mode should  also
use HA setting ? Because in my test case without using zookeeper HA ,
if the YarnApplicationMasterRunner/Jobmanager is failed or killed
,yarn can only restart the YarnApplicationMasterRunner/Jobmanager
program but no job graph is submitted to the Jobmanager again.
