flume-ng开发自己的source两种方法

第一种方法;继承AbstractSource抽象类并实现EventDrivenSource,Configurable接口：代码如下：

import org.apache.flume.conf.Configurable;

import org.apache.flume.source.AbstractSource;

public class TailSource extends AbstractSource implements EventDrivenSource,Configurable {

    public void configure(Context context) {}

    public synchronized void start() {}

    public synchronized void stop() {}

}

第二种方法：继承AbstractSource抽象类并实现Configurable, PollableSource接口：代码如下：

import org.apache.flume.conf.Configurable;


import org.apache.flume.source.AbstractSource;

public class TailSource extends AbstractSource implements Configurable,PollableSource {

    public void configure(Context context) {｝

    //这个方法在PollableSourceRunner类中会被一个线程不断的调用


    public Status process() throws EventDeliveryException {

      return null;

    ｝

    public synchronized void start() {｝

    public synchronized void stop() {｝
