Hbase Master

arunpoy — Fri, 02 Sep 2016 12:21:20 GMT

I have a 5 node HDP cluster and i want to add Hbase on to it. On how many nodes should i install HMaster. By default one node is enough i guess. Any thoughts on it. Also do i need to install phoenix query server, if so on how many nodes.

@ARUN if this is for production then add hbase master HA node. for PQS you can install on 1 load to start with. once the load increase then you can add more for load balancing.

The Phoenix Query Server (PQS) is an optional service. You only need to add it if you intend to use it.

PQS adds additional levels of connectivity into Apache Phoenix/HBase, but is not required for Phoenix access. Like Sunile points out, you can easily add this service to your installation later as the need/desire arises.
