Class	Description
BinStorageInputFormat
BinStorageOutputFormat
BinStorageRecordReader	Treats keys as offset in file and value as line.
BinStorageRecordWriter
BufferedPositionedInputStream
FileLocalizer
FileLocalizer.DataStorageInputStreamIterator
FileLocalizer.FetchFileRet
FileSpec	A simple class that specifies a file name and storage function which is used to read/write it
InterRecordReader	A record reader used to read data written using InterRecordWriter It uses the default InterSedes object for deserialization.
InterRecordWriter	A record reader used to write data compatible with InterRecordWriter It uses the default InterSedes object for serialization.
InterStorage	LOAD FUNCTION FOR PIG INTERNAL USE ONLY! This load function is used for storing intermediate data between MR jobs of a pig query.

NullableIntWritable
NullableLongWritable
NullablePartitionWritable	NullablePartitionWritable is an adaptor class around PigNullableWritable that adds a partition index to the class.
NullableText
NullableTuple
NullableUnknownWritable	This class can be used when data type is 'Unknown' and there is a need for PigNullableWritable object.
PigFile
PigNullableWritable	A base class for all types that pig uses to move data between map and reduce.
ReadToEndLoader	This is wrapper Loader which wraps a real LoadFunc underneath and allows to read a file completely starting a given split (indicated by a split index which is used to look in the List returned by the underlying InputFormat's getSplits() method).
SequenceFileInterStorage	Store tuples (BinSedesTuples, specifically) using sequence files to leverage sequence file's compression features.
SequenceFileInterStorage.SequenceFileTupleOutputFormat
TFileRecordReader	A record reader used to read data written using InterRecordWriter It uses the default InterSedes object for deserialization.
TFileRecordWriter	A record reader used to write data compatible with InterRecordWriter It uses the default InterSedes object for serialization.
TFileStorage	LOAD FUNCTION FOR PIG INTERNAL USE ONLY! This load function is used for storing intermediate data between MR jobs of a pig query.
