Class Summary

Class	Description
GiraphHCatInputFormat	Provides functionality similar to HCatInputFormat, but allows for different data sources (vertex and edge data).
HCatalogEdgeInputFormat<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>	HCatalog EdgeInputFormat for reading edges from Hive/Pig.
HCatalogEdgeInputFormat.HCatalogEdgeReader<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>	EdgeReader for HCatalogEdgeInputFormat.
HCatalogEdgeInputFormat.SingleRowHCatalogEdgeNoValueReader<I extends org.apache.hadoop.io.WritableComparable>	HCatalogEdgeInputFormat.HCatalogEdgeReader for tables holding a complete edge in each row where the edges contain no data other than IDs they point to.
HCatalogEdgeInputFormat.SingleRowHCatalogEdgeReader<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>	HCatalogEdgeInputFormat.HCatalogEdgeReader for tables holding a complete edge in each row.
HCatalogVertexInputFormat<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	Abstract class that users should subclass to load data from a Hive or Pig table.
HCatalogVertexOutputFormat<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	Abstract class that users should subclass to store data to Hive or Pig table.
HCatalogVertexOutputFormat.HCatalogVertexWriter<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	Abstract class that users should subclass based on their specific vertex output.
HCatalogVertexOutputFormat.MultiRowHCatalogVertexWriter<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	HCatalogVertexWriter to write each vertex in multiple rows.
HCatalogVertexOutputFormat.SingleRowHCatalogVertexWriter<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	HCatalogVertexWriter to write each vertex in each row.
HCatalogVertexValueInputFormat<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable>	HCatalog VertexValueInputFormat for reading vertex values from Hive/Pig.
HCatGiraphRunner	Hive Giraph Runner
HiveUtils	Utilities and helpers for working with Hive tables.
