  6. def createDirectory(root: String): File

    Create a directory inside the given parent directory.

    Create a directory inside the given parent directory. The directory is guaranteed to be newly created, and is not marked for automatic deletion.

  7. def createTempDir(root: String = ...): File

    Create a temporary directory inside the given parent directory.

  8. def deleteRecursively(file: File): Unit

    Delete a file or directory and its contents recursively.

    Delete a file or directory and its contents recursively. Don't follow directories if they are symlinks. Throws an exception if deletion is unsuccessful.

  36. def startServiceOnPort[T](startPort: Int, startService: (Int) ⇒ (T, Int), conf: SparkConf, serviceName: String = ""): (T, Int)

    Attempt to start a service on the given port, or fail after a number of attempts.

    Attempt to start a service on the given port, or fail after a number of attempts. Each subsequent attempt uses 1 + the port used in the previous attempt (unless the port is 0).

    startPort

    The initial port to start the service on.

    startService

    Function to start service on a given port. This is expected to throw java.net.BindException on port collision.

    conf

    A SparkConf used to get the maximum number of retries when binding to a port.

    serviceName

    Name of the service.
