You need zookeeper and kafka to run at the same time, so being in the directory where you have
kafka installed run the command for zookeeper in one terminal
bin/zookeeper-server-start.sh cong/zookeeper.properties
And kafka in another one
bin/kafka-server-start.sh cong/server.properties
Open another terminal (3 up to this point), and create a topic for kafka
bin/kafka-topics.sh {create {zookeeper localhost:2181 {replication-factor 1 {partitions
1 {topic tweets
Once the topic is created, go to the directory where you have the Ribbit application and run the
application
nodejs app.js
Then open another terminal and go to the directory where you have the spark application and run
the jar le
/usr/local/spark/bin/spark-submit {class TwitterStreaming {master local[4] target/streaming-
1.0.jar
In total 4 terminals need to be opened: one for the zookeeper server, another for the kafka server,
another to run the nodejs application (app.js) and another to run the spark application.
