Kyle R Stehbens commented on PHOENIX-6119:
------------------------------------------
I believe an elegant solution to this would be to split the ZK quorum servers
by the comma, and append the default port to the members that are missing one,
just as hbase does when constructing the ZK url here:

> This is because it is appending an extra default zookeeper port :2181 even
> though the zookeeper quorum specifies ports for each host.
> This happens at this line of code:
> [https://github.com/apache/phoenix/blob/f5cc0ad49f13283fefccddf1b187da95eecdb423/phoenix-core/src/main/java/org/apache/phoenix/util/QueryUtil.java#L439]
> Because the port here is always passed as the default port, and not as null
> if the ZK quorum already contains ports.
> Passing null for the port here will force the downstream connection utils to
> skip appending the port portion of the URL.
>
> This exception results in no statistics ever being populated in the system
> stats table for any phoenix tables/indices when using a zookeeper quorum with
> ports specified.
