Hi, i am using the " per-job YARN session " mode deploy flink job on yarn. The document https://ci.apache.org/projects/flink/flink-docs-release-1.5/ops/jobmanager_high_availability.html#yarn-cluster-high-availability 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. THANKS
