我有一个 Flink v1.2、3 个 JobManagers、2 个 TaskManagers 的设置。我想将 hdfs 用于后端状态和检查点以及 zookeeper storageDir
state.backend：文件系统
state.backend.fs.checkpointdir: hdfs:///[ip:port]/flink-checkpoints
state.checkpoints.dir: hdfs:///[ip:port]/external-checkpoints
高可用性：zookeeper
高可用性.zookeeper.storageDir: hdfs:///[ip:port]/recovery
在我登录的 JobManager 中，我有

Hadoop 作为单节点集群安装在我在设置中设置的 VM 上。为什么 Flink 要求配置额外的参数？（顺便说一句，它们不在官方文档中）
