## Package org.apache.hadoop.mapreduce.lib.partition

Interface Summary
InputSampler.Sampler<K,V> | Interface to sample using an `InputFormat`.

Class Summary
BinaryPartitioner<V> | Partition `BinaryComparable` keys using a configurable part of the bytes array returned by `BinaryComparable.getBytes()`.
HashPartitioner<K,V> | Partition keys by their `Object.hashCode()`.
InputSampler<K,V> | Utility for collecting samples and writing a partition file for `TotalOrderPartitioner`.
InputSampler.IntervalSampler<K,V> | Sample from s splits at regular intervals.
InputSampler.RandomSampler<K,V> | Sample from random points in the input.
InputSampler.SplitSampler<K,V> | Samples the first n records from s splits.
KeyFieldBasedComparator<K,V> | This comparator implementation provides a subset of the features provided by the Unix/GNU Sort.
KeyFieldBasedPartitioner<K2,V2> | Defines a way to partition keys based on certain key fields (also see `KeyFieldBasedComparator`.
TotalOrderPartitioner<K extends WritableComparable<?>,V> | Partitioner effecting a total order by reading split points from an externally generated source.
