帮我生成一个flink读取HDFS多文件的代码

可以使用以下代码来读取HDFS上的多个文件：val env = StreamExecutionEnvironment.getExecutionEnvironment
val hdfsURI = "hdfs://<your-namenode-host>:<port>/"
val filePaths = env.readTextFile(hdfsURI + "path/to/files/*.txt")filePaths.flatMap { line =>
val fields = line.split("\\s+")
fields.map { field =>
(field, field.length)
}
}
.print()env.execute("Read multiple HDFS files")
