Description

Creating this JIRA from mail thread
https://lists.apache.org/thread.html/5029f1f09c95a76b6e60a0f80e6f145dedf0b51cfdc08b964fb3b060@%3Cuser.phoenix.apache.org%3E

I'm using DriverManager.getConnection(url, properties) using following properties

url -> "jdbc:phoenix:thin:url=http://prabhu-3.novalocal:8765;serialization =PROTOBUF"  

properties -> 
0 = {java.util.Hashtable$Entry@1491} "user" -> "phoenixuser" 
1 = {java.util.Hashtable$Entry@1492} "password" -> 
2 = {java.util.Hashtable$Entry@1493} "url" -> "jdbc:phoenix:thin:url=http://prabhu-3.novalocal:8765;serialization =PROTOBUF" 
3 = {java.util.Hashtable$Entry@1494} "hbase.client.retries.number" -> "4" 
4 = {java.util.Hashtable$Entry@1495} "driver" -> "org.apache.phoenix.jdbc.PhoenixDriver"  

With the above propert/setting/config it returns a connection to the URL specified, but it also modifies my properties object to following

properties -> 
0 = {java.util.Hashtable$Entry@2361} "serialization" -> "PROTOBUF" 
1 = {java.util.Hashtable$Entry@2362} "user" -> "phoenixuser" 
2 = {java.util.Hashtable$Entry@2363} "password" -> 
*3 = {java.util.Hashtable$Entry@2364} "url" -> "http://prabhu-3.novalocal:8765 <http://prabhu-3.novalocal:8765>"* 
4 = {java.util.Hashtable$Entry@2365} "hbase.client.retries.number" -> "4" 
5 = {java.util.Hashtable$Entry@2366} "driver" -> "org.apache.phoenix.jdbc.PhoenixDriver"   

The above only happens if I'm using thin-client. Is this the expected behaviour ?

I plan to use this "properties" object after getting the connection for something else.

Also, I'm using following in my maven dependency "org.apache.phoenix:phoenix-server-client:4.7.0-HBase-1.1"
