Hi Sonali, This was something that I had some questions about originally as well. In terms of required components then yes, for any size of Samza deployment you will need all those pieces.
In terms of actual deployment, from what I understand from the LinkedIn guys they do run Samza on a dedicated YARN grid that also has a Kafka broker collocated on each node. These decisions though appear to be more down to convenience than a hard requirement. In my own setup I have existing ZooKeeper and Kafka clusters that I'm pointing Samza at but do need to run a dedicated YARN grid because my Hadoop cluster has a pre-2.2 version of YARN running on it. So if you have existing components you can reuse them, if not then repurposing the Hello Samza package is a good starting point to get all the things you want on the required hosts. Only caveat would be to not drop a ZK node on each host, the ZK quorum should follow the usual advice of an odd number of servers and likely no more than 3, 5 or 7 depending on your deployment size.

I understand that Samza comes with yarn,kafka and zookeeper out of the box. Is that the model just for a standalone/local configuration. What if I want a bigger cluster? Do I have to install yarn, kafka and zookeeper separately? Any suggestions would be great!
