K - The type of key. If an Avro type, it must be wrapped in an AvroKey.V - The type of value. If an Avro type, it must be wrapped in an AvroValue.public class AvroKeyValueWithMetadataOutputFormat<K,V>
extends org.apache.avro.mapreduce.AvroOutputFormatBase<K,V>
Since Avro container files can only contain records (not key/value pairs), this output format puts the key and value into an Avro generic record with two fields, named 'key' and 'value'.
The keys and values given to this output format may be Avro objects wrapped in
AvroKey or AvroValue objects. The basic Writable types are
also supported (e.g., IntWritable, Text); they will be converted to their corresponding
Avro types.
