我正在尝试在像这样的YARN群集上启动Flink作业
flink run -m yarn-cluster -yn 2 -yjm 1024 -ytm 2048 -c myclass flink-test-1.0-SNAPSHOT
不幸的是，作业失败并显示无法联系JobManager的消息。相同的作业在仅由一个节点（伪群集）组成的YARN群集上成功运行。 flink-yarn-yaml指向Hadoop配置的正确位置。该作业的YARN应用程序日志也不包含可能出错的有价值信息。客户端和工作节点之间的通信应该没有任何问题，因为其他与集群相关的技术，如Spark，Hive，MR可以正常工作。
你能否提示这里可能出现的问题？我还试图在flink-conf.yaml中启用zookeeper领导者选举，但也没有帮助。
