linux - Flume 在 Linux 中运行失败

Question

当我将 flume 安装到 Linux 中时，我在运行 flume 时收到了一些警告我按照这个过程安装了一个水槽。

>> sudo tar -xvf flume-ng-1.1.0-cdh4.0.1\(1\).tar.gz
>> export PATH=/home/hduser/downloads/flume-1.1.0- cdh4.0.1/bin:$PATH
>> $ sudo cp conf/flume-conf.properties.template conf/flume.conf

为了运行水槽，我使用了这个命令

>> $ bin/flume-ng agent -n agent -f conf/flume.conf

但是它显示了一些警告

hadoopmaster@HadoopMaster:/home/hduser/downloads/flume-ng$ sudo bin/flume-ng agent -n agent -f conf/flume.conf
Warning: No configuration directory set! Use --conf <dir> to override.
Warning: JAVA_HOME not set!

log4j:WARN No appenders could be found for logger (org.apache.flume.lifecycle.LifecycleSupervisor).

Answer 1

如果您想从 log4j appender 获取输出，则需要将 -c conf 添加到命令行。例如:

export JAVA_HOME=... # recommended to set JAVA_HOME properly
./bin/flume-ng agent -c conf -f conf/flume.conf -n agent
