Colin Ma commented on HIVE-15468:
---------------------------------

[~teddy.choi], I think the improvement is useful to support complex date types 
in Hive vectorization. Do you still work on these improvements, and can you 
share the status, thanks.

> Currently Hive's vectorized execution engine only supports scalar types, as 
> documented here: 
> https://cwiki.apache.org/confluence/display/Hive/Vectorized+Query+Execution.
> To be complete, we should add support for complex types as well.
