I have setup a hive environment with Kerberos security enabled on a Linux server (Red Hat). And I need to connect from a remote windows machine to hive using JDBC.

If you were running your code in Linux, I would simply point to that post -- i.e. you must use System properties to define Kerberos and JAAS configuration, from conf files with specific formats.
And you have to switch the debug trace flags to understand subtile configuration issue (i.e. different flavors/versions of JVMs may have different syntax requirements, which are not documented, it's a trial-and-error process).
But on Windows there are additional problems:
hadoop.home.dir and java.library.path pointing to the Hadoop home dir and its bin sub-dir respectivelyOn the top of that, the Apache Hive driver has compatibility issues -- whenever there are changes in the wire protocol, newer clients cannot connect to older servers.
So I strongly advise you to use the Cloudera JDBC driver for Hive for your Windows clients. The Cloudera site just asks your e-mail.
After that you have a 80+ pages PDF manual to read, the JARs to add to your CLASSPATH, and your JDBC URL to adapt according to the manual.
Side note: the Cloudera driver is a proper JDBC-4.x compliant driver, no need for that legacy Class.forName()...
