Class DummyPartition

java.lang.Object

org.apache.hadoop.hive.ql.metadata.Partition

org.apache.hadoop.hive.ql.metadata.DummyPartition

All Implemented Interfaces:

Serializable

public class DummyPartition
extends Partition

A Hive Table Partition: is a fundamental storage unit within a Table. Currently, Hive does not support hierarchical partitions - For eg: if partition ds=1, hr=1 exists, there is no way to access ds=1 Hierarchical partitions are needed in some cases, for eg. locking. For now, create a dummy partition to satisfy this
