             Summary: Implement vectorized support for CASE conditional expression
                 Key: HIVE-5757
                 URL: https://issues.apache.org/jira/browse/HIVE-5757
             Project: Hive
          Issue Type: Sub-task
            Reporter: Eric Hanson


Implement full, end-to-end support for CASE in vectorized mode, including new VectorExpression class(es), VectorizationContext translation to a VectorExpression, and unit tests for these, as well as end-to-end ad hoc testing. An end-to-end .q test is recommended but optional.

This is high priority because CASE is a fairly popular expression.
