Subject Re: What is the phoenix-queryserver-client-4.14.2-HBase-1.4.jar?
Date Thu, 19 Sep 2019 17:53:08 GMT
A) phoenix-4.14.2-HBase-1.4-thin-client.jar

Just A) is good enough, Josh, you had a sample program here:
https://github.com/joshelser/phoenix-queryserver-jdbc-client

And the phoenix-4.14.2-HBase-1.4-thin-client.jar already contains the
org.apache.phoenix.queryserver.client.Driver
