> Cygnus startup error, ClassNotFoundExceptiom: com.telefonica.iot.cygnus.sinks.NGSITestSink
> +Description:+
> I'm following the quick start guide described here.
> I performed the following steps in a centos6 virtual machine to install cygnus and I got an ClassNotFoundException:
> yum install java-1.7.0-openjdk-devel
> export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk.x86_64 (to .bash_profile)
> cat > /etc/yum.repos.d/fiware.repo <<EOL

> yum install cygnus
> To configure and test the installation I filled in the /usr/cygnus/conf/agent_test.conf with
