类 HdfsSequentialTextSink

java.lang.Object

org.apache.pulsar.io.hdfs3.AbstractHdfsConnector

org.apache.pulsar.io.hdfs3.sink.HdfsAbstractSink<K,V>

org.apache.pulsar.io.hdfs3.sink.seq.HdfsAbstractSequenceFileSink<java.lang.Long,java.lang.String,org.apache.hadoop.io.LongWritable,org.apache.hadoop.io.Text>

org.apache.pulsar.io.hdfs3.sink.seq.HdfsSequentialTextSink

所有已实现的接口:

java.lang.AutoCloseable, org.apache.pulsar.io.core.Sink<java.lang.String>

public class HdfsSequentialTextSink
extends HdfsAbstractSequenceFileSink<java.lang.Long,java.lang.String,org.apache.hadoop.io.LongWritable,org.apache.hadoop.io.Text>

This Sink should be used when the records are originating from a sequential source, and we want to retain the record sequence.This class uses the record's sequence id as the sequence id in the HDFS Sequence File if it is available, if not a sequence id is auto-generated for each new record.
