SequenceFileRDDFunctions

class SequenceFileRDDFunctions[K, V] extends Logging with Serializable

Extra functions available on RDDs of (key, value) pairs to create a Hadoop SequenceFile, through an implicit conversion. Note that this can't be part of PairRDDFunctions because we need more implicit parameters to convert our keys and values to Writable.

Import org.apache.spark.SparkContext._ at the top of their program to use these functions.

    Output the RDD as a Hadoop SequenceFile using the Writable types we infer from the RDD's key and value types.

    Output the RDD as a Hadoop SequenceFile using the Writable types we infer from the RDD's key and value types. If the key or value are Writable, then we use their classes directly; otherwise we map primitive types such as Int and Double to IntWritable, DoubleWritable, etc, byte arrays to BytesWritable, and Strings to Text. The path can be on any Hadoop-supported file system.
