12. def getOrCreate(checkpointPath: String, creatingFunc: () ⇒ StreamingContext, hadoopConf: Configuration = new Configuration(), createOnError: Boolean = false): StreamingContext

    Either recreate a StreamingContext from checkpoint data or create a new StreamingContext.

    Either recreate a StreamingContext from checkpoint data or create a new StreamingContext. If checkpoint data exists in the provided checkpointPath, then StreamingContext will be recreated from the checkpoint data. If the data does not exist, then the StreamingContext will be created by called the provided creatingFunc.

    checkpointPath

    Checkpoint directory used in an earlier StreamingContext program

    creatingFunc

    Function to create a new StreamingContext

    hadoopConf

    Optional Hadoop configuration if necessary for reading from the file system

    createOnError

    Optional, whether to create a new StreamingContext if there is an error in reading checkpoint data. By default, an exception will be thrown on error.
