PQS (Phoenix Query Server) install on worker node

[#1]

Does PQS have any dependency on data (non-OS) disks of worker node? If PQS is installed on slave/worker node (note - JBOD disk organization), is there any impact to the service when replacing a data disk?

Are there any pros/cons of installing PQS on master node vs worker node ? Ambari docs seem to indicate that both are supported

You can run in both. It's always good idea to segregate the services. I see no issues on deploying the PQS in worker node "make sure that you have multiple PQS in case particluar worker gets decomissioned"
