HadoopWriter

class HadoopWriter extends Logging with HadoopMapRedUtil with Serializable

Internal helper class that saves an RDD using a Hadoop OutputFormat. This is only public because we need to access this class from the spark package to use some package-private Hadoop functions, but this class should not be used directly by users.

Saves the RDD using a JobConf, which should contain an output key class, an output value class, a filename to write to, etc, exactly like in a Hadoop MapReduce job.
