Cygnus 시작 오류, ClassNotFoundExceptiom : com.telefonica.iot.cygnus.sinks.NGSITestSink

here에 설명 된 빠른 시작 가이드를 따르고 있습니다. Cygnus 시작 오류, ClassNotFoundExceptiom : com.telefonica.iot.cygnus.sinks.NGSITestSink

내가 니를 설치하려면 centos6 가상 머신에서 다음 단계를 수행하고 난 ClassNotFoundException가 있어요 :

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 
[Fiware] 
name=FIWARE repository 
baseurl=http://repositories.testbed.fi-ware.eu/repo/rpm/x86_64/ 
gpgcheck=0

EOL 

yum install cygnus

구성하고 내가

cygnus-ngsi.sources = http-source 
cygnus-ngsi.sinks = test-sink 
cygnus-ngsi.channels = test-channel 

cygnus-ngsi.sources.http-source.channels = test-channel

I로 /usr/cygnus/conf/agent_test.conf 채워 설치를 테스트하려면를 명령을 수행 :

/usr/cygnus/bin/cygnus-flume-ng agent --conf /usr/cygnus/conf/ -f /usr/cygnus/conf/agent_test.conf -n cygnus-ngsi -Dflume.root.logger=INFO,console

어떤 버전이 설치되어 있는지 확인할 수 있습니까? 그것에 대한 로그에는 추적 로그가 있습니다. 당신은'rpm -qa | grep cygnus' 또는. – frb

죄송합니다. 더 이상이 인스턴스가 없습니다. 나는 StackOverFlow 커뮤니티에 새로 왔으며이 질문을 삭제하는 것을 잊었다. 나는 지금 그것을 할 것이다. –

예, 닫으십시오. 감사! – frb

설치 오류 일 수 있습니다. docker로 설치할 때이 문제가 없습니다.
