Class DeepParquetHiveMapInspector

java.lang.Object

org.apache.hadoop.hive.ql.io.parquet.serde.AbstractParquetMapInspector

org.apache.hadoop.hive.ql.io.parquet.serde.DeepParquetHiveMapInspector

All Implemented Interfaces:

Cloneable, MapObjectInspector, ObjectInspector, SettableMapObjectInspector

public class DeepParquetHiveMapInspector
extends AbstractParquetMapInspector

The DeepParquetHiveMapInspector will inspect an ArrayWritable, considering it as a Hive map.
It can also inspect a Map if Hive decides to inspect the result of an inspection.
When trying to access elements from the map it will iterate over all keys, inspecting them and comparing them to the desired key.
