Hi Jins,
Check out
https://community.hortonworks.com/articles/9377/deploying-the-phoenix-query-server-in-production-e.html
which should cover a bit of this (specifically, via HAProxy).
I wrote this prior to the ZK-based discovery and client-driven load
balancer which has showed up recently. As for what PQS needs from a load
balancer, the only requirement is for sticky sessions. With that, and
relatively stable backend servers, a dumb HTTP load balancer should work
just fine.

Hi,
I am trying to add a load balancer for query server and after reading
documentation, I am a little confused on which option to pick. go with a
traditional load balancer ( thinking of ELB) or the inbuilt zookeeper
based load balancer. Is there an advantage of using ELB over the
zookeeper based one ? ( I am not using Kerberos, so thats not an issue).
Thanks,
Jins George
