-------------------------------------------

I don't have ability to test this one on Windows, but I've verified that the test passes on Linux and I trust [~venkatnrangan]. Hence +1.

> SQOOP-1138 fixes output directory handling in incremental imports in Sqoop and added a few tests.   The ORM class file and jar file created used the default name QueryResult and repeated deletion and recreation of the jar file caused NPE when the JarFileLoader was loading the Jar file in one of the tests because of Windows IO related issues with the following stack trace
