Package org.apache.hadoop.io

Added Classes
BloomMapFile	This class extends MapFile and provides very much the same functionality.
BloomMapFile.Reader
BloomMapFile.Writer

 

Changed Classes and Interfaces
ArrayFile.Writer	Write a new array file.
ArrayWritable	A Writable for arrays containing instances of a class.
BinaryComparable	Interface supported by org.apache.hadoop.io.WritableComparable types supporting ordering/permutation by a representative set of bytes.
BytesWritable	A byte sequence that is usable as a key or value.
DefaultStringifier	DefaultStringifier is the default implementation of the Stringifier interface which stringifies the objects using base64 encoding of the serialized version of the objects.
MD5Hash	A Writable for MD5 hash values.
MapFile	A file-based map from keys to values.
MapFile.Reader	Provide access to an existing map.
MapFile.Writer	Writes a new map.
MapWritable	A Writable Map.
MultipleIOException	Encapsulate a list of IOException into an IOException
RawComparator	A Comparator that operates directly on byte representations of objects.
SequenceFile.CompressionType	The compression type used to compress key/value pairs in the SequenceFile
SequenceFile.Metadata	The class encapsulating with the metadata of a file.
SequenceFile.Reader	Reads key/value pairs from a sequence-format file.
SequenceFile.Sorter	Sorts key/value pairs in a sequence-format file.
SetFile.Writer	Write a new set file.
SortedMapWritable	A Writable SortedMap.
Stringifier	Stringifier interface offers two methods to convert an object to a string representation and restore the object given its string representation.
Text	This class stores text using standard UTF8 encoding.
WritableComparable	A Writable which is also Comparable
WritableComparator	A Comparator for
WritableFactories	Factories for non-public writables.
WritableName	Utility to permit renaming of Writable implementation classes without invalidiating files that contain their class name.
