Cygnus cpu assembly error

I wanted to use Fiware cygnus to save data from a context broker to a CKAN instance. I already created the browser orion context brom vm which is orion-psb-image-R5.4 version 1.7.0 and ckan virtual machine on Fiware cloud. I started installing fiware cygnus knowing that cygnus is based on both cygnus-common and cygnus-ngsi. So I started by downloading fiware-cygnus https://github.com/telefonicaid/fiware-cygnus , then I started building cygnus-common successfully using maven 3.2.5. But when I started building cygnus-ngsi it failed, although I tried many ways to solve this problem but Noone worked. Here's what I did in detail.

First, installing Apache Flume as described here http://fiware-cygnus.readthedocs.io/en/1.3.0/cygnus-common/installation_and_administration_guide/install_from_sources/index.html

$ wget http://www.eu.apache.org/dist/flume/1.4.0/apache-flume-1.4.0-bin.tar.gz
 tar xvzf apache-flume-1.4.0-bin.tar.gz
$ mv apache-flume-1.4.0-bin APACHE_FLUME_HOME
$ mv APACHE_FLUME_HOME/lib/httpclient-4.2.1.jar APACHE_FLUME_HOME/lib/httpclient-4.2.1.jar.old
$ mv APACHE_FLUME_HOME/lib/httpcore-4.2.1.jar APACHE_FLUME_HOME/lib/httpcore-4.2.1.jar.old
$ mv APACHE_FLUME_HOME/lib/libthrift-0.7.0.jar APACHE_FLUME_HOME/lib/libthrift-0.7.0.jar.old
$ mkdir -p APACHE_FLUME_HOME/plugins.d/cygnus/
$ mkdir APACHE_FLUME_HOME/plugins.d/cygnus/lib
$ mkdir APACHE_FLUME_HOME/plugins.d/cygnus/libext

      

        
        
        
      

    

second, downloading fiware-cygnus and creating cygnus-common:

git clone https://github.com/telefonicaid/fiware-cygnus.git

cd fiware-cygnus/cygnus-common

mvn clean compile exec:exec assembly:single

cp target/cygnus-common-1.7.0-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext 

mvn install:install-file -Dfile=/usr/cygnus/plugins.d/cygnus/libext/cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar -DgroupId=com.telefonica.iot -DartifactId=cygnus-common -Dversion=1.7.0 -Dpackaging=jar -DgeneratePom=false

cp target/classes/cygnus-flume-ng /usr/cygnus/bin/cygnus-flume-ng

      

        
        
        
      

    

then I started building cygnus-ngsi as follows

cd cygnus-ngsi

mvn clean compile exec:exec assembly:single

      

        
        
        
      

    

and I got these results when building it:

[INFO] Building cygnus-ngsi 1.7.0_SNAPSHOT

I copied the generated jar file to /usr/cygnus/plugins.d/cygnus/libext as described in the same link above by running:

cp cygnus-common/target/cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar    /usr/cygnus/plugins.d/cygnus/libext 

      

        
        
        
      

    

also i copied the jar file to the maven repository path to make sure everything is installed correctly by running the command

cp cygnus-common/target/cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar   ~/.m2/repository/com/telefonica/iot/cygnus-common/1.7.0

      

        
        
        
      

    

Now I have in ~ / .m2 / repository / COM / Telefonica / IOP / Cygnus-common / 1.7.0 directory two jars, and <T26> and cygnus-common-1.7.0.jar

, as well as USR / Cygnus / plugins. d / cygnus / libext containing them, and in fact I don't know if there would be a problem of having two jars inside either of those directories.

I also thought the cygnus-ngsi pom.xml file might be part of the problem .. and here's the cygnus-ngsi pom.xml:

Now I want to know what could be causing this crash. All I want to do is install the cygnus agent to use ckansink by configuring the agent_.conf file to provide the required ckan options, then start cygnus. and I know that this process will not complete unless cygnus-ngsi is successfully created

EDIT: I have now tried to remove all previous cygnus files by running

sudo rpm -e -vv --allmatches --nodeps --noscripts --notriggers cygnus
sudo rpm -e -vv --allmatches --nodeps --noscripts --notriggers cygnus-ngsi

      

        
        
        
      

    

And then I installed cygnus-common and cygnus-ngsi 1.7.0 using rpm and they were installed successfully. then I configured the required ckan parameters in the / usr / cygnus / conf / agent _1.conf file.

Now the problem is when I start cygnus by running

/usr/cygnus/bin/cygnus-flume-ng agent --conf /usr/cygnus/conf/ -f /usr/cygnus/conf/agent_1.conf -n cygnusagent -Dflume.root.logger=INFO,console

      

        
        
        
      

    

I am getting these logs ending only with the jetty server listening on 8081 like this:

and when I test cygnus from another terminal using the test.sh file, I get connection refused.

[centos@orcb2 ~]$ ./notification.sh http://localhost:5050/notify
* About to connect() to localhost port 5050 (#0)
*   Trying ::1... Connection refused
*   Trying 127.0.0.1... Connection refused
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host

      

        
        
        
      

    

Although the configuration files should be correct, as I think they look like this:

• These are my agent_1.conf file options and ckan config options:

  =============================================
  source configuration
  
  cygnus-ngsi.sources.http-source.channels = hdfs-channel mysql-channel ckan-channel mongo-channel sth-channel kafka-channel dynamodb-channel postgresql-channel
  
  
  cygnus-ngsi.sources.http-source.type = org.apache.flume.source.http.HTTPSource
  
  cygnus-ngsi.sources.http-source.port = 5050
  
  cygnus-ngsi.sources.http-source.handler = com.telefonica.iot.cygnus.handlers.NGSIRestHandler
  
  cygnus-ngsi.sources.http-source.handler.notification_target = /notify
  
  cygnus-ngsi.sources.http-source.handler.default_service = default
  
  cygnus-ngsi.sources.http-source.handler.default_service_path = /
  
  cygnus-ngsi.sources.http-source.interceptors = ts gi
  
  cygnus-ngsi.sources.http-source.interceptors.ts.type = timestamp
  
  cygnus-ngsi.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.NGSIGroupingInterceptor$Builder
  
  cygnus-ngsi.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf
  
  
  
     # ============================================
      NGSICKANSink configuration
  cygnus-ngsi.sinks.ckan-sink.channel = ckan-channel
  
  cygnus-ngsi.sinks.ckan-sink.type =com.telefonica.iot.cygnus.sinks.NGSICKANSink
  
  cygnus-ngsi.sinks.ckan-sink.enable_grouping = false
  
  cygnus-ngsi.sinks.ckan-sink.enable_name_mappings = false
  
  cygnus-ngsi.sinks.ckan-sink.enable_encoding = false
  
  cygnus-ngsi.sinks.ckan-sink.api_key = xxxxxxxx-xxxx-xxxxxx-xxxxx
  cygnus-ngsi.sinks.ckan-sink.ckan_host = http://130.206.120.212
  
  cygnus-ngsi.sinks.ckan-sink.ckan_port = 8080
  
  cygnus-ngsi.sinks.ckan-sink.ckan_viewer = recline_grid_view
  
  cygnus-ngsi.sinks.ckan-sink.orion_url = http://localhost:1026
  
  cygnus-ngsi.sinks.ckan-sink.attr_persistence = row
  
  cygnus-ngsi.sinks.ckan-sink.ssl = false
  
  cygnus-ngsi.sinks.ckan-sink.batch_size = 100
  
  cygnus-ngsi.sinks.ckan-sink.batch_timeout = 30
  
  cygnus-ngsi.sinks.ckan-sink.batch_ttl = 10
  
  cygnus-ngsi.sinks.ckan-sink.backend.max_conns = 500
  
  cygnus-ngsi.sinks.ckan-sink.backend.max_conns_per_route = 100
  
        
  
          
          
          
        
  
      

and this is my cygnus_instance_1.conf

CYGNUS_USER=cygnus

CONFIG_FOLDER=/usr/cygnus/conf

CONFIG_FILE=/usr/cygnus/conf/agent_1.conf

AGENT_NAME=cygnusagent

LOGFILE_NAME=cygnus.log

ADMIN_PORT=8081

POLLING_INTERVAL=30

      

        
        
        
      

    

So, is missing from all configurations and what can be committed to allow the httpsource to accept my notification requests?
