使用flume搜集服务器log到hdfs

xiyou

　　将多个logs服务器上的log搜集到hdfs服务器上，多个logs服务上的flume-sink和hdfs服务器上的flume-source都是avro类型，hdfs服务器上的flume-sink是hdfs类型
　　

　　
　　Flume部署文档
　　系统要求：
　　Java 运行时环境

　　
　　部署方式：
　　在logs和hdfs服务器上下载并解压flume包
　　
　　下载flume包并解压：
　　http://mirror.bit.edu.cn/apache/flume/1.4.0/apache-flume-1.4.0-bin.tar.gz
　　
logs服务器flume配置
　　进入解压后的flume目录，修改配置文件：
　　1.      Cp  conf/flume-env.sh.template conf/flume-env.sh
　　在conf/flume-env.sh中添加
　　JAVA_HOME=” JAVA HOME DIR”
　　
　　2.      在conf目录下创建flume.conf配置文件,添加以下内容
　　修改agent.sources.loggerSource.command 值
