Fiware cygnus build failure

Question

I wanted to use Fiware cygnus to persist data from the context broker into a CKAN instance. I've already created an orion context broker vm which is orion-psb-image-R5.4 version 1.7.0 and a ckan VM on Fiware cloud. I began to install fiware cygnus knowing that the cygnus is based on both cygnus-common and cygnus-ngsi . So, i started by downloading the fiware-cygnus https://github.com/telefonicaid/fiware-cygnus , then i began building cygnus-common successfully using maven 3.2.5 . But when i started to build cygnus-ngsi it failed although i've tried many ways to solve this but Noone worked . Here's what i have done in details .

Firstly 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

secondly , downloading fiware-cygnus and building 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 bulding cygnus-ngsi as follows

cd cygnus-ngsi

mvn clean compile exec:exec assembly:single

and i got these results on building it:

I copied the generated jar file to the /usr/cygnus/plugins.d/cygnus/libext as explained 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 have copied the jar file to maven repository path to make sure everything is set properly 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 the ~/.m2/repository/com/telefonica/iot/cygnus-common/1.7.0 directory two jars, the cygnus-common-1.7.0_SNAPSHOT-jar-with-dependencies.jar and cygnus-common-1.7.0.jar as well as the usr/cygnus/plugins.d/cygnus/libext directory containing them and actually i don't know whether the existence of two jars inside either of these directories would make a problem or not.

i also thought that the cygnus-ngsi pom.xml file could be a part of the problem .. and here's the pom.xml of cygnus-ngsi:

Now i want to know what may cause this failure . All i want to do is to set a cygnus agent to use the ckansink by configuring the agent_.conf file with providing the necessary ckan parameters and then start the cygnus. and i know that this process wouldn't be completed unless the cygnus-ngsi was built successfuly

EDIT : Now, i tried removing 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 the cygnus-common and cygnus-ngsi 1.7.0 using the rpm and they were succesfully installed. then i configured the necessary ckan parameters in the /usr/cygnus/conf/agent_1.conf file.

The problem now is when i start the 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 get these logs ending only with the jetty server listening on 8081 as follows:

and when i test the cygnus from another terminal with a notification.sh testing file i get connection refused.

[centos@orcb2 ~]$ ./notification.sh http://localhost:5050/notify

*   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 are supposed to be correct as i think and they are as follows:

• these are my agent_1.conf file source and ckan configuration parameters :

  =============================================
  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.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 in the whole configurations and what could be fixed to let the httpsource accept my notification requests ?

Answer 1

From this command:

cp target/cygnus-common-1.1.0-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext

It seems you have built cygnus-common release 1.1.0 (Is it right? I mean, is there a cygnus-common-1.1.0-jar-with-dependencies.jar file within target/ directory?)

Nevertheless, in the next command you have tried to install cygnus-common release 1.7.0_SNAPSHOT (with dependencies):

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

Thus one of the above commands is wrong: both must refer to the same release.

One question: once cloned the github repo, did you checkout to a specific version as stated in the documentation?

$ git clone https://github.com/telefonicaid/fiware-cygnus.git
$ cd fiware-cygnus
$ git checkout <branch>

Such a <branch> could be master (the lastest development, not recommended), 1.7.0 (the latest official release), 1.6.0...

So, use always a specific version for all the components, even use the appropiate documentation version (for instance, the documentation link you have posted refers to release 1.3.0, while you were trying to build cygnus-common 1.1.0 but installing 1.7.0...).

PS: there is an easy way of installing the latest release (at the moment of writing this, 1.7.0): using a RPM from FIWARE repo.

EDIT 1: [Once installation problems are fixed and the question has been edited regarding a startup problem]

If you are not able to send a simulated notification to Cygnus it is because Cygnus has not started properly. You can check the logs at /var/log/cygnus/cygnus.log and get more details. Anyway, some remarks to your configuration:

Regarding agent_1.conf:

• I'm missing source, channel and sink declarations. In addition, I'm missing the channel configuration. I guess you consciously omitted it, for simplicity.
• Source channels can be limited to ckan-channel.

Regarding cygnus_instance_1.conf:

• AGENT_NAME must match the one used in agent_1.conf, i.e. cygnus-ngsi.

Additionally, once installed, did you started Cygnus service? Just to be sure :)

$ sudo service cygnus start

Answer 2

Edit 2 : i've solved the connection refused error after i noticed that the default naming in cygnus_instance_1.conf is cygnusagent meanwhile the used one inside the agent_1.conf was cygnus-ngsi and i changed the name in the instance file. and now i get successfull http response , but still the data isn't persisted in ckan as i noticed some errors in the cygnus logs (whether i started cygnus by either the "service cygnus start" or the other long startup command) .

Now, this is the successful response as follows:

  [centos@orcb2 ~]$ ./notification.sh http://localhost:5050/notify
    * About to connect() to localhost port 5050 (#0)
    *   Trying ::1... connected
    * Connected to localhost (::1) port 5050 (#0)

    < Transfer-Encoding: chunked
    < Server: Jetty(6.1.26)
    < 
    * Connection #0 to host localhost left intact
    * Closing connection #0

and here are the important parts regarding the errors in the new logs when i start the cygnus send notification:

These are the channel , source and sink definitions in the agent.conf file

agent.sources = seqGenSrc
agent.channels = memoryChannel
agent.sinks = loggerSink

agent.sources.seqGenSrc.type = seq

agent.sources.seqGenSrc.channels = memoryChannel

agent.sinks.loggerSink.type = logger

agent.sinks.loggerSink.channel = memoryChannel

agent.channels.memoryChannel.type = memory


agent.channels.memoryChannel.capacity = 100

and this this is the ckan channel configuration

cygnus-ngsi.channels.ckan-channel.type = memory
cygnus-ngsi.channels.ckan-channel.capacity = 1000
cygnus-ngsi.channels.ckan-channel.transactionCapacity = 100

Regarding the ckan side , I want to know if there are additional procedures in the Ckan more than creating the account to persist the ngsi events.. do i have to manually create an organization and a dataset with its datastore for receiving ngsi events ? or are the fiware service and service path mapped into an organization and dataset with creation of their datastore and resource automatically on sending ngsi events ? i just want to make sure if i understood this correctly.

Now , what do you think i shall do to solve these errors ?
