ZeroMQ plugin for flume-ng

flume-ng-zeromq

Custom flume-ng source to pull data from ZeroMQ. Note that it assumes PUSH/PULL message scheme. To build use mvn package (note that Java 8 and maven are needed).

Install to flume-ng

This was tested with: flume-ng 1.8/1.7/1.6 and jermq 0.4.4/0.4.3.

The generated JAR needs to be copied to the the plugin directory:

<flume-ng-home>/plugins.d/flume-ng-zeromq/lib

The jeromq (zeromq inplementation in Java) JAR should also be added there as an external dependency:

<flume-ng-home>/plugins.d/flume-ng-zeromq/libext

jeromq JAR could be fetched from here, or built from source.

Configuration Sample

a1.sources.r1.type = org.apache.flume.source.zeromq.ZeroMQSource
a1.sources.r1.port = 5555
a1.sources.r1.hostname = 127.0.0.1

Test Node

Note that it usese vagrant, which have to be first installed for the test node to work.

To start the test node first get into the vagrant directory, and then run vagrant up. To stop the node, run vagrant halt from the same place. Once the test node is up, you can login to it by using vagrant ssh (from the vagrant direcotry). Inside the node, use:

apache-flume-1.8.0-bin/bin/flume-ng agent --conf conf --conf-file example.conf --name a1 -Dflume.root.logger=DEBUG,consol -Dlog4j.configuration=file:///home/vagrant/log4j.properties

To execute the flume-ng agent with the zeromq configuration.

From a separate shell inside the node, run the zmq-client.py script in order to send data into flume.
