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" </P> Tue, 05 Jan 2016 10:30:16 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/PQS-Phoenix-Query-Server-install-on-worker-node/m-p/101338#M14026 nsabharwal 2016-01-05T10:30:16Z
