Great answer, Aleksandr!
Also worth mentioning there is only ever one active HBase Master at a
time. If you have multiple started, one will be active as the master and
the rest will be waiting as a standby in case the current active master
dies for some reason (expectedly or unexpectedly).

Hello.
- Phoenix libs should be installed only on RegionServers.
- QueryServer - it's up to you, PQS can be installed anywhere you want
- No. QueryServer is using ZK quorum to get everything it needs
- If you need to balance traffic with multiply PQSs - then yes, but
again - it's up to you. It is not required multiply PQSs if you have
multiply HBase masters.

Our cluster used to have one hbase master, now a secondary is added.
For phonenix, what changes should we make?
- do we have to install new hbase libraries on the new hbase
master node?
- do we need to install new query server on the hbase master?
- any configuration changes should we make?
- do we need an ELB for the query server?
Thanks
