Class Summary

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.
FileInputFormat<K,V>	A base class for file-based InputFormats.
FileSplit	A section of an input file.
FixedLengthInputFormat	FixedLengthInputFormat is an input format used to read input files which contain fixed length records.
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.
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.
SequenceFileInputFormat<K,V>	An InputFormat for SequenceFiles.
SequenceFileRecordReader<K,V>	An RecordReader for SequenceFiles.
TextInputFormat	An InputFormat for plain text files.

Exception Summary

Exception	Description
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.
