我有一个flinkv1.2的设置，3个jobmanagers，2个taskmanagers。我想使用hdfs的后端状态和检查点和zookeeper storagedir
state.backend:文件系统
state.backend.fs.checkpointdir:hdfs://[ip:port]/flink检查点
state.checkpoints.dir:hdfs:///[ip:port]/外部检查点
高可用性：zookeeper
高可用性.zookeeper.storagedir:hdfs:///[ip:port]/恢复
在jobmanager中我记录了

hadoop作为一个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(它们不在官方文件中（顺便说一句）

我认为你必须使用这个网址模式 hdfs://[ip:port]/flink-checkpoints 用于访问hdfshostname:port specification.
如果您正在使用 fs.defaultFS 在hadoop配置中，不需要输入namenode的详细信息。
