Hive JDBC and invalid SSL certificates

[Daisuke Goto <da...@att.net>]

Hello: I am a Hive JDBC user and I am new to Hive and Java.  I am currently
trying to use the JDBC driver to pull data from a test server that issues a
SSL certificate for *.azurehdinsight.net but I can only reach the server
through an internal ip address 10.*.*.*.  I figured that I need to modify
\jdbc\src\java\org\apache\hive\jdbc\HiveConnection.java to accept invalid
certificates.  I found that lines 465 - 506 are responsible for
establishing a SSL connection.  I am wondering if anyone could either
modify the code for me to accept an invalid certificate or give me some
pointers.  I'd never want to ask for something without making contributions
first but at this moment, I need your help.  I'd greatly appreciate your
input.
