Uses of JobConfigurable in org.apache.hadoop.mapred

Subinterfaces of JobConfigurable in org.apache.hadoop.mapred

interface	Mapper<K1,V1,K2,V2> Maps input key/value pairs to a set of intermediate key/value pairs.
interface	MapRunnable<K1,V1,K2,V2> Expert: Generic interface for Mappers.
interface	Partitioner<K2,V2> Partitions the key space.
interface	Reducer<K2,V2,K3,V3> Reduces a set of intermediate values which share a key to a smaller set of values.

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

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

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

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 @link org.apache.hadoop.mapred.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 pairs.
class	TotalOrderPartitioner<K extends WritableComparable<?>,V> Partitioner effecting a total order by reading split points from an externally generated source.
