public class DemoPackTuples2
extends Object

Demo that packs the sample collection into a SequenceFile as Tuple objects with complex internal structure. The records are stored in a local SequenceFile; this file can then be transfered over to HDFS to serve as the the input to DemoWordCountTuple2.

Each value in the SequenceFile is a tuple with two fields:

• the first field of the tuple is an Integer with the field name "length"; its value is the length of the record in number of characters.
• the second field of the tuple is a ListWritable with the field name "tokens"; its value is a list of tokens that comprise the text of the record.
