error log says

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.activemq.transport.TransportFactory.bind

OS Ubuntu 14.04

Looks like jar file missing. Which version of Falcon? Could you check if you have activemq jar file under Falcon home directory? e.g.

[root@sandbox falcon]# ls server/webapp/falcon/WEB-INF/lib/*activemq*

server/webapp/falcon/WEB-INF/lib/activemq-core-5.4.3.jar server/webapp/falcon/WEB-INF/lib/activemq-protobuf-1.1.jar

Hi @yzheng

Thank you for your response.

I found 2 extra activemq jar in /usr/hdp/current/oozie-client directory.

Removing them solved the the problem.
