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.
