Question:
Cygnus stop at start

Description:
I've installed Cygnus on Ubuntu 14.04 using this guide and when i proceed to start cygnus through(correctly filled):

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>] &

I get this output:

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/'

-Djava.library.path= com.telefonica.iot.cygnus.nodes.CygnusApplication -f /usr/cygnus/conf/agent_1.conf -n cygnusagent

Starting an ordered shutdown of Cygnus
Stopping sources

Where is the problem?
