Improvement to SequenceFileLoader (NullWritable and Delimiter)
--------------------------------------------------------------

                 Key: PIG-2494
                 URL: https://issues.apache.org/jira/browse/PIG-2494
             Project: Pig
          Issue Type: Improvement
          Components: piggybank
    Affects Versions: 0.9.1
         Environment: All
            Reporter: Ted Malaska
            Priority: Minor


I wanted to add two features to SequenceFileLoader.
1.      I added a delimiter so it will act more like PigStorage, in that it 
will Split the value if it is a type Text (chararray).
2.      I added the option of the key being a NullWritable.  I wanted to be 
able to process my Hive files in both Hive and Pig, but because my Hive 
sequence files have a NullWritable key I could not make this work with the 
current implementation of SequenceFileLoader.
