dbutils。fsprovides utilities for working with FileSystems. Most methods in this package can take either a DBFS path (e.g., "/foo" or "dbfs:/foo"), or another FileSystem URI. For more info about a method, use dbutils.fs.help("methodName"). In notebooks, you can also use the %fs shorthand to access DBFS. The %fs shorthand maps straightforwardly onto dbutils calls. For example, "%fs head --maxBytes=10000 /file/path" translates into "dbutils.fs.head("/file/path", maxBytes = 10000)". fsutils cp(from: String, to: String, recurse: boolean = false): boolean -> Copies a file or directory, possibly across FileSystems head(file: String, maxBytes: int = 65536): String -> Returns up to the first 'maxBytes' bytes of the given file as a String encoded in UTF-8 ls(dir: String): Seq -> Lists the contents of a directory mkdirs(dir: String): boolean -> Creates the given directory if it does not exist, also creating any necessary parent directories mv(from: String, to: String, recurse: boolean = false): boolean -> Moves a file or directory, possibly across FileSystems put(file: String, contents: String, overwrite: boolean = false): boolean -> Writes the given String out to a file, encoded in UTF-8 rm(dir: String, recurse: boolean = false): boolean -> Removes a file or directory mount mount(source: String, mountPoint: String, encryptionType: String = "", owner: String = null, extraConfigs: Map = Map.empty[String, String]): boolean -> Mounts the given source directory into DBFS at the given mount point mounts: Seq -> Displays information about what is mounted within DBFS refreshMounts: boolean -> Forces all machines in this cluster to refresh their mount cache, ensuring they receive the most recent information unmount(mountPoint: String): boolean -> Deletes a DBFS mount point updateMount(source: String, mountPoint: String, encryptionType: String = "", owner: String = null, extraConfigs: Map = Map.empty[String, String]): boolean -> Similar to mount(), but updates an existing mount point instead of creating a new one

dbutils。數據provides utilities for understanding and interpreting datasets. This module is currently in preview and may be unstable. For more info about a method, use dbutils.data.help("methodName"). summarize(df: Object, precise: boolean): void -> Summarize a Spark DataFrame and visualize the statistics to get quick insights
