Description

I used tcpdump to display the network traffic: 

[root@fe01 ~]# beeline 
Beeline version 0.13.1-cdh5.3.2 by Apache Hive 
beeline> !connect jdbc:hive2://fe01.sectest.poc:10000/default 
Connecting to jdbc:hive2://fe01.sectest.poc:10000/default 
Enter username for jdbc:hive2://fe01.sectest.poc:10000/default: tdaranyi 
Enter password for jdbc:hive2://fe01.sectest.poc:10000/default: ********* 
(I entered "cleartext" as the password) 

The tcpdump in a different window 
[e-mail]:~$ sudo tcpdump -n -X -i lo port 10000 
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

We rely on the user supplied configuration to decide whether to open an SSL socket or a Plain one. Instead we can negotiate this information from the HS2 and connect accordingly.
