天鹅座停在开始
Cygnus stop at start
我已经使用 this guide 在 Ubuntu 14.04 上安装了 Cygnus，当我通过（正确填充）继续启动 cygnus 时：
nohup APACHE_FLUME_HOME/bin/cygnus-flume-ng agent --conf APACHE_FLUME_HOME/conf -f APACHE_FLUME_HOME/conf/cygnus.conf -n cygnusagent -Dflume.root.logger=INFO,LOGFILE [-p <mgmt-if-port>] [-t <polling-interval>] &
我得到这个输出：
Warning: JAVA_HOME is not set!
+ exec /usr/bin/java -Xmx20m -cp '/etc/flume/apache-flume-1.4.0-bin/conf:/etc/flume/apache-flume-1.4.0-bin/lib/*:/etc/flume/apache-flume-1.4.0-bin/plugins.d/cygnus/lib/*'
