Uses of InputFormat in org.apache.hadoop.mapred

Classes in org.apache.hadoop.mapred that implement InputFormat

Modifier and Type	Class and Description
class	FileInputFormat<K,V> A base class for file-based InputFormat.
class	FixedLengthInputFormat FixedLengthInputFormat is an input format used to read input files which contain fixed length records.
class	KeyValueTextInputFormat An InputFormat for plain text files.
class	MultiFileInputFormat<K,V> An abstract InputFormat that returns MultiFileSplit's in MultiFileInputFormat.getSplits(JobConf, int) method.
class	SequenceFileAsBinaryInputFormat InputFormat reading keys, values from SequenceFiles in binary (raw) format.
class	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.
class	SequenceFileInputFilter<K,V> A class that allows a map/red job to work on a sample of sequence files.
class	SequenceFileInputFormat<K,V> An InputFormat for SequenceFiles.
class	TextInputFormat An InputFormat for plain text files.
