Class AvroSequenceFileInputFormat.AvroSequenceFileRecordReader

java.lang.Object

org.apache.hadoop.mapreduce.RecordReader<K,V>

org.apache.avro.mapreduce.AvroSequenceFileInputFormat.AvroSequenceFileRecordReader

All Implemented Interfaces:

Closeable, AutoCloseable

Enclosing class:

AvroSequenceFileInputFormat<K,V>

protected class AvroSequenceFileInputFormat.AvroSequenceFileRecordReader
extends org.apache.hadoop.mapreduce.RecordReader<K,V>

Reads records from a SequenceFile that supports Avro data.

This class is based on Hadoop's SequenceFileRecordReader, modified to construct an AvroSequenceFile.Reader instead of a SequenceFile.Reader.
