4.2. 启动Apache Flume Client

Apache Flume Client可以运行在任何安装有Apache Flume环境的主机上，只要和运行Apache Flume Agent的主机网络上相通。 运行命令如下：

flume-ng avro-client -H \

我们在测试环境中针对Apache Flume Client的启停编写了shell脚本，该脚本会将运行目录下所有的文件传输到Apache Flume Agent。启动脚本如下：

#!/bin/bash

local_file_dir=/home/hadoop/mr_data/hw

local_bak_dir=/home/hadoop/mr_data/back_up/hw avro_host=10.32.147.241 avro_port=4141

status_file=/home/hadoop/apache-flume-1.2.0/conf/status_file

if [ ! -d \

echo \ exit 1 fi

if [ ! -d \

echo \ exit 2 fi

if [ ! -f \ touch \

echo $(date) > \fi

echo \cd \if [ 0 -ne $? ]; then

echo \ exit 3 fi

while [ -f $status_file ] do

for filename in $(ls -lrt | awk '{print $9}') do

echo \

if [ \ continue fi

if [[ -n \ echo \

flume-ng avro-client -H \-p \-filename

\

echo \

mv \ fi done

sleep 10

done

停止脚本如下：

#!/bin/bash

status_file=status_file

echo \

if [ -f \ rm -f \ if [ 0 -eq $? ]; then

echo \ else

echo \ fi else

echo \fi

4.3. 停止Apache Flume

Apache Flume并没有提供停止的命令，所以要停止Apache Flume需要kill进程号

[hadoop@cassdb 20120917]$ ps -ef | grep flume [hadoop@cassdb 20120917]$ kill -9 进程号

4.4. Apache Flume命令

Usage: ./flume-ng [options]...

commands:

help display this help text agent run a Flume agent avro-client run an avro Flume client version show Flume version info

global options:

--conf,-c use configs in directory --classpath,-C append to the classpath

--dryrun,-d do not actually start Flume, just print the command -Dproperty=value sets a JDK system property value

agent options:

--conf-file,-f specify a config file (required)

--name,-n the name of this agent (required) --help,-h display help text

--filename,-F text file to stream to avro source [default: std input]

--headerFile,-R headerFile containing headers as key/value pairs on each new line --help,-h display help text

Note that if directory is specified, then it is always included first in the classpath.

5. 其它

本手册只对Apache Flume的简单数据流进行了配置（这种配置也是我们目前测试系统中使用的），Apache Flume还支持很多其它的配置方法，其它配置方法的描述请参见：
