Cygnus startup error: ClassNotFoundException

Question

My environment is VM with CentOS 6.6

I followed the instruction in https://github.com/telefonicaid/fiware-cygnus/blob/master/doc/quick_start_guide.md to install Cygnus.

Answer 1

From Cygnus 0.8.1 the interceptor type for the grouping mechanism is not named DestinationExtractor anymore, but GroupingInterceptor. This is detailed in the Cygnus 0.8.2 README (showing relevant parts):

cygnusagent.sources.http-source.interceptors = ts gi
cygnusagent.sources.http-source.interceptors.ts.type = timestamp
cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf

Nevertheless, the Quick Start Guide must be updated, nice catch!
