Class Summary

Class	Description
BinaryRecordReader<K extends Writable,V extends Writable>	Reads every possible pair of values from two underlying record readers.
BinarySpatialInputFormat<K extends Writable,V extends Writable>	An input format that reads a pair of files simultaneously and returns a key for one of them and the value as a pair of values.
DefaultBlockFilter	A default implementation for BlockFilter that returns everything.
FileSplitUtil	A set of method and algorithms used to support management of file splits.
GridOutputFormat<S extends Shape>
GridOutputFormat2<S extends Shape>
GridOutputFormat3<S extends Shape>
GridRecordWriter<S extends Shape>	A record writer that can be used in MapReduce programs to write an index file where the key is the cell ID and the value is the shape to write to that cell.
GridRecordWriter2<S extends Shape>	A record writer that can be used in MapReduce programs.
GridRecordWriter3<S extends Shape>	A record writer to be used to write the output of MapReduce programs to a spatial index.
PairWritable<T extends Writable>	A class that stores a pair of objects where both are writable
RandomInputFormat<S extends Shape>
RandomShapeGenerator<S extends Shape>	A record reader that generates random shapes in a specified area out of the blue.
