Class Summary

Class	Description
AndReduce	ReduceOperation for calculating the AND function over boolean values.
KryoWrappedReduceOperation<S,R>	Reduce operation which wraps reduced value in KryoWritableWrapper, so we don't need to worry about it being writable
LongXorReduce	ReduceOperation that XORs (^) values together.
MaxPairReducer<L extends org.apache.hadoop.io.Writable,R extends org.apache.hadoop.io.WritableComparable>	Aggregating PairWritable<L, R>, by taking pair with largest second value.
MaxReduce<T extends org.apache.hadoop.io.WritableComparable>	Reducer for calculating max of values
MinReduce<T extends org.apache.hadoop.io.WritableComparable>	Reducer for calculating min of values
OrReduce	ReduceOperation for calculating the OR function over boolean values.
PairReduce<S1,R1 extends org.apache.hadoop.io.Writable,S2,R2 extends org.apache.hadoop.io.Writable>	Combines two individual reducers, to create a single reducer of pairs that reduces each of them individually.
SumReduce<T extends org.apache.hadoop.io.Writable>	Reducer for calculating sum of values
