flume使用四个案例(监听端口，监听文件并传到另外一台电脑，监听文件夹，监听文件夹并将数据保存到hdfs)

• • 1.案例一监听端口到界面
  • • 1.1监听端口配置信息
    • 1.2 执行
    • 1.3 监听端口测试
  • 2监听文件并传到另外一台电脑上界面
  • • 2.1配置信息(监听文件->avro->nodez001->logger)
    • 2.2 执行
    • 2.3 测试
  • 3 监听文件夹到界面
  • • 3.1 配置信息
    • 3.2 执行
    • 3.3 测试
  • 4 监听文件到hdfs
  • • 4.1 配置信息
    • 4.2 执行
    • 3.3 测试
  • 未完待续
