          Description

          Hi

          We installed Cygnus on our FIWARE cloud server and are getting the
          following error message:

          SSH command:
          /usr/local/apache-flume-1.4.0-bin/bin/flume-ng agent --conf

          -Dflume.root.logger=INFO,console

          Error:

            As the log says:

            Running HTTP Server found in source: http-source before I started one.Will not attempt to start.

            This means there is another Http server running on the configured port for the source (typically, a previous Cygnus execution not stopped or killed apropriatelly). Check it by doing:

            $ netstat -nap | grep <your_configured_port>

            That will show you, if any, the PID listening on that port. If it is a previous Cygnus instance, just kill it:

            $ kill -9 <PID>

            If it is not a previous Cygnus instance, do not kill the process since it amy be useful for any other application. Simply move to another free TCP port. This can be done at the configuration (in your case: /usr/local/apache-flume-1.4.0-bin/conf/cygnus.conf):

            orionagent.sources.<your_http_source_name>.port = <typically_5050_change_it>

            Hope this helps
