Review request for hive, Carl Steinbach and Ashutosh Chauhan.


Description
-------

If the class path size is more than 8K then we can’t set the environment 
variable so some of the test cases are failing on Windows. Remove the duplicate 
JAR entries from the class path to reduce the chance of exceeding the 8K limit.


This addresses bug HIVE-3494.
