Package org.apache.hadoop.mapreduce.lib.input

Added Classes and Interfaces
CombineFileInputFormat	An abstract InputFormat that returns i InputFormat#getSplits(JobContext) method.
CombineFileRecordReader	A generic RecordReader that can hand out different recordReaders for each chunk in a CombineFileSplit A CombineFileSplit can combine data chunks from multiple files.
CombineFileSplit	A sub-collection of input files.
DelegatingInputFormat	An InputFormat that delegates behavior of paths to multiple other InputFormats.
DelegatingMapper	An Mapper that delegates behavior of paths to multiple other mappers.
DelegatingRecordReader	This is a delegating RecordReader which delegates the functionality to the underlying record reader in TaggedInputSplit
KeyValueLineRecordReader	This class treats a line in the input as a key/value pair separated by a separator character.
KeyValueTextInputFormat	An InputFormat for plain text files.
MultipleInputs	This class supports MapReduce jobs that have multiple input paths with a different InputFormat and Mapper for each path
NLineInputFormat	NLineInputFormat which splits N lines of input as one split.
SequenceFileAsBinaryInputFormat	InputFormat reading keys values from SequenceFiles in binary (raw) format.
SequenceFileAsBinaryInputFormat. SequenceFileAsBinaryRecordReader	Read records from a SequenceFile as binary (raw) bytes.
SequenceFileAsTextInputFormat	This class is similar to SequenceFileInputFormat except it generates SequenceFileAsTextRecordReader which converts the input keys and values to their String forms by calling toString() method.
SequenceFileAsTextRecordReader	This class converts the input keys and values to their String forms by calling toString() method.
SequenceFileInputFilter	A class that allows a map/red job to work on a sample of sequence files.
SequenceFileInputFilter. Filter	filter interface
SequenceFileInputFilter. FilterBase	base class for Filters
SequenceFileInputFilter. MD5Filter	This class returns a set of records by examing the MD5 digest of its key against a filtering frequency f.
SequenceFileInputFilter. PercentFilter	This class returns a percentage of records The percentage is determined by a filtering frequency f using the criteria record# % f == 0.
SequenceFileInputFilter. RegexFilter	Records filter by matching key to regex

 

Changed Classes
LineRecordReader	Treats keys as offset in file and value as line.
