Class Summary

Class	Description
GraphInputFormat	A graph based input-specification for MapReduce jobs which splits an underlying root table by region and by the scans resulting from a given query, then provides graph record readers for each split which assemble and serve data graphs to client mapper extensions.
GraphMapper<KEYOUT,VALUEOUT>	Supplies fully realized data graphs as the input value to MapReduce Mapper client subclasses, the input key being an HBase row key bytes and the input value being a GraphWritable assembled from one or more underlying HBase table(s)/row(s).
GraphMapReduceSetup	Mapreduce Job setup utility for GraphMapper and GraphReducer and extensions.
GraphRecordReader	Iterates over HBase root table data for the current TableSplit, assembling data graphs based on the detailed selection criteria within a given query.
GraphRecordRecognizer	Iterates over HBase root table data for the current TableSplit, assembling data graphs based on the detailed selection criteria within a given query.
GraphReducer<KEYIN,VALUEIN,KEYOUT>
GraphServiceDelegate
