Subject Re: How should Samza be run on AWS?
Date Wed, 05 Aug 2015 18:03:51 GMT
I wrote several  Ansible playbooks to deploy YARN (without HDFS), Zookeeper
and Kafka to EC2 for deploying Samza jobs. If you know ansible those
scripts may be helpful. You can find them at I was planning to add
document describing these scripts but could do it yet. I looked at EMR
also, but as I remember EMR job deployment model doesn't work with current
scripts provided by Samza.

I used R3 instances for Kafka and C3 instances for YARN. As I remember I
could get close to 1million msg/s with 3 node Kafka cluster running on
r3.xlarge instance and 2 (or 4) node YARN cluster running 4 stream tasks
per job.
