在spark独立集群中启用高可用性（ha）时，我面临一个非常奇怪的问题。
我已经配置了3个spark主机，并通过以下步骤在zookeeper中注册它们：
创建配置文件 ha.conf 内容如下：
spark.deploy.recoverymode=缩放管理员
spark.deploy.zookeeper.url=zk_host:2181
spark.deploy.zookeeper.dir=/spark
通过将此属性文件作为参数传递给启动主脚本来启动所有3个主脚本，如下所示：
./start-master.sh-h localhost-p 17077--webui端口18080--properties文件ha.conf
这样，我得到了所有3Spark主启动和登记在Zookeeper。
如果我杀死活动主机，那么所有正在运行的应用程序都会被新的活动主机接收。
如果任何一个Spark主控器（例如：localhost:17077)关闭/不工作，我使用以下命令提交申请：
./bin/spark submit--class wordcount--masterspark://localhost：17077，h2:27077，h3:37077--部署模式集群--conf spark.cores.max=1~/testspark-0.0.1-snapshot.jar/user1/test.txt
理想情况下，应该去积极的主人，应该工作良好，因为只有一个主人是下降，其他人正在工作，但我得到例外情况如下：

任何帮助/线索/建议都将不胜感激。请帮助我理解这一点，我已经找到了这样的问题，但找不到任何东西。

当我以集群模式提交应用程序时，我面临这个问题，如果我以客户机模式提交应用程序，则没有问题。
