Uses of InterfaceStability.Stable in org.apache.hadoop.mapreduce.lib.input

Classes in org.apache.hadoop.mapreduce.lib.input with annotations of type InterfaceStability.Stable

class	CombineFileInputFormat<K,V> An abstract InputFormat that returns CombineFileSplit's in InputFormat.getSplits(JobContext) method.
class	CombineFileRecordReader<K,V> A generic RecordReader that can hand out different recordReaders for each chunk in a CombineFileSplit.
class	CombineFileSplit A sub-collection of input files.
class	KeyValueLineRecordReader This class treats a line in the input as a key/value pair separated by a separator character.
class	KeyValueTextInputFormat An InputFormat for plain text files.
class	MultipleInputs This class supports MapReduce jobs that have multiple input paths with a different InputFormat and Mapper for each path
class	NLineInputFormat NLineInputFormat which splits N lines of input as one split.
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	SequenceFileAsTextRecordReader This class 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.
