[jira] [Created] (HIVE-4694) Fix ORC TestVectorizedORCReader testcase for Timestamps

Gopal V created HIVE-4694:
-----------------------------

             Summary: Fix ORC TestVectorizedORCReader testcase for Timestamps
                 Key: HIVE-4694
                 URL: https://issues.apache.org/jira/browse/HIVE-4694
             Project: Hive
          Issue Type: Bug
          Components: Tests
            Reporter: Gopal V
            Assignee: Gopal V
            Priority: Minor


ORC vectorized tests were not testing for timestamps correctly.

java.sql.Timestamp is a confusing API, because of the mix of getTime() & getNanos() usage. Though it might look like they return independent values, getTime() includes part of the value already present in getNanos().

Please view the implementation code for the confusion

Fix in HIVE-4681 caused test-failures, which needs the test to be fixed.
