---------------------------------
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.
