Class AvroGenericRecordWritable

java.lang.Object

org.apache.hadoop.hive.serde2.avro.AvroGenericRecordWritable

All Implemented Interfaces:

org.apache.hadoop.io.Writable

public class AvroGenericRecordWritable
extends Object
implements org.apache.hadoop.io.Writable

Wrapper around an Avro GenericRecord. Necessary because Hive's deserializer will happily deserialize any object - as long as it's a writable.
