com.hazelcast.mapreduce.aggregation.impl	This package contains a set of predefined aggregation implementations
com.hazelcast.mapreduce.impl	This package contains the default implementation for the map reduce framework internals.
com.hazelcast.mapreduce.impl.client	This package contains request and response classes for communication between cluster members and Hazelcast native clients
com.hazelcast.mapreduce.impl.operation	This package contains all remote operations that are needed to control work on supervising or worker nodes.
com.hazelcast.mapreduce.impl.task	This package contains the base implementation for a standard map reduce job.

Uses of Mapper in com.hazelcast.mapreduce

Subinterfaces of Mapper in com.hazelcast.mapreduce

interface

LifecycleMapper<KeyIn,ValueIn,KeyOut,ValueOut> The LifecycleMapper interface is a more sophisticated version of Mapper normally used for complexer algorithms with a need of initialization and finalization.

Classes in com.hazelcast.mapreduce that implement Mapper

class

LifecycleMapperAdapter<KeyIn,ValueIn,KeyOut,ValueOut> The abstract LifecycleMapperAdapter superclass is used to ease building mappers for the Job.

Methods in com.hazelcast.mapreduce with parameters of type Mapper

<KeyOut,ValueOut> MappingJob<KeyIn,KeyOut,ValueOut>

Job.mapper(Mapper<KeyIn,ValueIn,KeyOut,ValueOut> mapper) Defines the mapper for this task.
