             Summary: Implement vectorized support for COALESCE conditional expression
                 Key: HIVE-5759
                 URL: https://issues.apache.org/jira/browse/HIVE-5759
             Project: Hive
          Issue Type: Sub-task
            Reporter: Eric Hanson


Implement full, end-to-end support for COALESCE 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.

This is lower priority than IF and CASE but it is still a fairly popular expression.
