Class CompositeAccumuloRowIdFactory<T extends AccumuloCompositeRowId>

java.lang.Object

org.apache.hadoop.hive.accumulo.serde.DefaultAccumuloRowIdFactory

org.apache.hadoop.hive.accumulo.serde.CompositeAccumuloRowIdFactory<T>

Type Parameters:

T -

All Implemented Interfaces:

AccumuloRowIdFactory

public class CompositeAccumuloRowIdFactory<T extends AccumuloCompositeRowId>
extends DefaultAccumuloRowIdFactory

AccumuloRowIdFactory designed for injection of the AccumuloCompositeRowId to be used to generate the Accumulo rowId. Allows for custom AccumuloCompositeRowIds to be specified without overriding the entire ObjectInspector for the Hive row.
