Uses of JobConfigurable in org.apache.hadoop.mapred.lib

Classes in org.apache.hadoop.mapred.lib that implement JobConfigurable

Modifier and Type	Class	Description
class	BinaryPartitioner<V>	Partition BinaryComparable keys using a configurable part of the bytes array returned by BinaryComparable.getBytes().
class	ChainMapper	The ChainMapper class allows to use multiple Mapper classes within a single Map task.
class	ChainReducer	The ChainReducer class allows to chain multiple Mapper classes after a Reducer within the Reducer task.
class	FieldSelectionMapReduce<K,V>	This class implements a mapper/reducer class that can be used to perform field selections in a manner similar to unix cut.
class	HashPartitioner<K2,V2>	Partition keys by their Object.hashCode().
class	IdentityMapper<K,V>	Implements the identity function, mapping inputs directly to outputs.
class	IdentityReducer<K,V>	Performs no reduction, writing all input values directly to the output.
class	InverseMapper<K,V>	A Mapper that swaps keys and values.
class	KeyFieldBasedComparator<K,V>	This comparator implementation provides a subset of the features provided by the Unix/GNU Sort.
class	KeyFieldBasedPartitioner<K2,V2>	Defines a way to partition keys based on certain key fields (also see KeyFieldBasedComparator.
class	LongSumReducer<K>	A Reducer that sums long values.
class	MultithreadedMapRunner<K1,V1,K2,V2>	Multithreaded implementation for MapRunnable.
class	NLineInputFormat	NLineInputFormat which splits N lines of input as one split.
class	RegexMapper<K>	A Mapper that extracts text matching a regular expression.
class	TokenCountMapper<K>	A Mapper that maps text values into <token,freq> pairs.
class	TotalOrderPartitioner<K,V>	Partitioner effecting a total order by reading split points from an externally generated source.
