> We've been doing some more testing after PHOENIX-3126 and, with the help of 
> [~arpitgupta] and [~harsha_ch], we've found an issue in a test between Storm 
> and Phoenix.
> Storm was configured to create a JDBC Bolt, specifying the principal and 
> keytab in the JDBC URL, relying on PhoenixDriver to do the Kerberos login for 
> them. After PHOENIX-3126, a ZK server blacklisted the host running the bolt, 
> and we observed that there were over 140 active ZK threads in the JVM.
> This results in a subtle change where every time the client tries to get a 
> new Connection, we end up getting a new UGI instance (because the 
> {{ConnectionQueryServicesImpl#openConnection()}} always does a new login).
> If users are correctly caching Connections, there isn't an issue (best as I 
> can presently tell). However, if users rely on the getting the same 
> connection every time (the pre-PHOENIX-3126), they will saturate their local 
> JVM with connections and crash.
