用户指南中的位，它向您展示如何设置收集器并对其进行写入http://archive.cloudera.com/cdh/3/flume/userguide/index.html#_tiering_flume_nodes_agents_and_collectors 具有以下配置：

host : console | agentSink("localhost",35853) ;
collector : collectorSource(35853) | console ;

我把它改成：

dataSource : console | agentSink("localhost") ;
dataCollector : collectorSource() | console ;

我将节点生成为：

flume node_nowatch -n dataSource
flume node_nowatch -n dataCollector

我在两个系统上尝试过：
cloudera自己的演示虚拟机运行在virtualbox中，内存为2gb。配有Flume0.9.4-cdh3u2
带有debian包和openjdk（不包括任何hadoop包）的ubuntults（lucid）作为虚拟机在virtualbox中运行，内存为2gb，如下所示https://ccp.cloudera.com/display/cdhdoc/flume+installation#flumeinstallation-安装FlumerPMordebiang包
以下是我所做的： flume dump 'collectorSource()' 导致

$ sudo netstat -anp | grep 35853
tcp6       0      0 :::35853                :::*                    LISTEN      3520/java
$ ps aux | grep java | grep 3520
1000      3520  0.8  2.3 1050508 44676 pts/0   Sl+  15:38   0:02 java -Dflume.log.dir=/usr/lib/flume/logs -Dflume.log.file=flume.log -Dflume.root.logger=INFO,console -Dzookeeper.root.logger=ERROR,console -Dwatchdog.root.logger=INFO,console -Djava.library.path=/usr/lib/flume/lib::/usr/lib/hadoop/lib/native/Linux-amd64-64 com.cloudera.flume.agent.FlumeNode -1 -s -n dump -c dump: collectorSource() | console;

我的假设是：

flume dump 'collectorSource()'

与运行配置相同：

dump : collectorSource() | console ;

然后用

flume node -1 -n dump -c "dump: collectorSource() | console;" -s
``` `dataSource : console | agentSink("localhost")` 导致

$ sudo netstat -anp | grep 35853
tcp6 0 0 :::35853 :::* LISTEN 3520/java

在两个virtualbox虚拟机中观察到的行为完全相同：
