Class	Description
CombineFileInputFormat<K,V>	An abstract InputFormat that returns CombineFileSplit's in InputFormat.getSplits(JobContext) method.
CombineFileRecordReader<K,V>	A generic RecordReader that can hand out different recordReaders for each chunk in a CombineFileSplit.
CombineFileRecordReaderWrapper<K,V>	A wrapper class for a record reader that handles a single file split.
CombineFileSplit	A sub-collection of input files.
CombineSequenceFileInputFormat<K,V>	Input format that is a CombineFileInputFormat-equivalent for SequenceFileInputFormat.
CombineTextInputFormat	Input format that is a CombineFileInputFormat-equivalent for TextInputFormat.
org.apache.hadoop.mapreduce.lib.input.CompressedSplitLineReader	Line reader for compressed splits Reading records from a compressed split is tricky, as the LineRecordReader is using the reported compressed input stream position directly to determine when a split has ended.
org.apache.hadoop.mapreduce.lib.input.DelegatingInputFormat<K,V>	An InputFormat that delegates behavior of paths to multiple other InputFormats.
org.apache.hadoop.mapreduce.lib.input.DelegatingMapper<K1,V1,K2,V2>	An Mapper that delegates behavior of paths to multiple other mappers.
org.apache.hadoop.mapreduce.lib.input.DelegatingRecordReader<K,V>	This is a delegating RecordReader, which delegates the functionality to the underlying record reader in TaggedInputSplit
FileInputFormat<K,V>	A base class for file-based InputFormats.
FileInputFormat.Counter	Deprecated.
FileInputFormatCounter
FileSplit	A section of an input file.
FixedLengthInputFormat	FixedLengthInputFormat is an input format used to read input files which contain fixed length records.
org.apache.hadoop.mapreduce.lib.input.FixedLengthRecordReader	A reader to read fixed length records from a split.
InvalidInputException	This class wraps a list of problems with the input, so that the user can get a list of problems together instead of finding and fixing them one by one.
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.
org.apache.hadoop.mapreduce.lib.input.LineRecordReader	Treats keys as offset in file and value as line.
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.
org.apache.hadoop.mapreduce.lib.input.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<K,V>	A class that allows a map/red job to work on a sample of sequence files.
org.apache.hadoop.mapreduce.lib.input.SequenceFileInputFilter.Filter	filter interface
org.apache.hadoop.mapreduce.lib.input.SequenceFileInputFilter.FilterBase	base class for Filters
org.apache.hadoop.mapreduce.lib.input.SequenceFileInputFilter.MD5Filter	This class returns a set of records by examing the MD5 digest of its key against a filtering frequency f.
org.apache.hadoop.mapreduce.lib.input.SequenceFileInputFilter.PercentFilter	This class returns a percentage of records The percentage is determined by a filtering frequency f using the criteria record# % f == 0.
org.apache.hadoop.mapreduce.lib.input.SequenceFileInputFilter.RegexFilter	Records filter by matching key to regex
SequenceFileInputFormat<K,V>	An InputFormat for SequenceFiles.
SequenceFileRecordReader<K,V>	An RecordReader for SequenceFiles.
org.apache.hadoop.mapreduce.lib.input.SplitLineReader
TextInputFormat	An InputFormat for plain text files.
org.apache.hadoop.mapreduce.lib.input.UncompressedSplitLineReader	SplitLineReader for uncompressed files.
