abstract class HadoopWriteConfigUtil[K, V] extends Serializable

Interface for create output format/committer/writer used during saving an RDD using a Hadoop OutputFormat (both from the old mapred API and the new mapreduce API)

Notes: 1. Implementations should throw IllegalArgumentException when wrong hadoop API is referenced; 2. Implementations must be serializable, as the instance instantiated on the driver will be used for tasks on executors; 3. Implementations should have a constructor with exactly one argument: (conf: SerializableConfiguration) or (conf: SerializableJobConf).
