JavaSDK设计规则

 

 JavaSDK提供两个事件触发方法,分别为onChargeSuccess和onChargeRefund。我们在java sdk中通过一个单独的线程来发送线程数据,这样可以减少对业务系统的延时性。

SDK测试

  启动集群上的hdfs+nginx+flume进程,通过模拟数据的发送然后将数据发送到nginx服务器中,查看最终是否在hdfs中有数据的写入。

命令:

   start-dfs.sh: 启动hdfs命令

   su root:切换用户

   service nginx restart: 启动nginx进程

   启动flume进程:

       进入flume安装根目录,执行命令:


flume-ng agent –conf ./conf/ –conf-file ./conf/test2.conf –name agent &
