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

             Summary: TestIncrementalImport fails with NPE on Windows
                 Key: SQOOP-1759
                 URL: https://issues.apache.org/jira/browse/SQOOP-1759
             Project: Sqoop
          Issue Type: Bug
    Affects Versions: 1.4.5
         Environment: Windows
            Reporter: Venkat Ranganathan
            Assignee: Venkat Ranganathan
             Fix For: 1.4.6


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

java.lang.RuntimeException: java.lang.NullPointerException

The fix is to explicitly specify a unique class name for the ORM class file generated (which is also the jar file name) generated
