Subject Re: Apache Spark data locality when integrating with Kafka
Date Sun, 07 Feb 2016 14:08:57 GMT
I would definitely try to avoid hosting Kafka and Spark on the same servers. 

Kafka and Spark will be doing alot of IO between them, so you'll want to
maximize on those resources and not share them on the same server. You'll
want each Kafka broker to be on a dedicated server, as well as your spark
master and workers. If you're hosting them on Amazon EC2 instances, then
you'll want these to be on the same availability zone, so you can benefit
from low latency in that same zone. If you're on a dedicated servers,
perhaps you'll want to create a VPC between the two clusters so you can,
again, benefit from low IO latency and high throughput.
