我正在尝试将后端状态设置为hdfs

val stateUri = "hdfs/path_to_dir"
val backend: RocksDBStateBackend = new RocksDBStateBackend(stateUri, true)
env.setStateBackend(backend)

我使用flink 1.7.0运行，具有以下依赖项（我尝试了所有组合）：

"org.apache.flink"    %% "flink-connector-filesystem"         % flinkV
"org.apache.flink"    % "flink-hadoop-fs"                     % flinkV
"org.apache.hadoop"   % "hadoop-hdfs"                         % hadoopVersion
"org.apache.hadoop"   % "hadoop-common"                       % hadoopVersion

但是，在运行jar时，出现以下错误：

Caused by: org.apache.flink.core.fs.UnsupportedFileSystemSchemeException: Could not find a file system implementation for scheme 'hdfs'. The scheme is not directly supported by Flink and no Hadoop file system to support this scheme could be loaded.

任何帮助都将不胜感激
