Teddy Choi commented on HIVE-4945:
----------------------------------
While writing this code, I found that even if the query was not running with
vectorization expressions, it returns the same .q.out file. So it makes hard to
check that vectorization expressions were used or not.
There is a way to check it. If vectorized expressions were used,
ExecDriver#job#getMapperClass() returns VectorExecMapper#class after calling
ExecDriver#execute(). Otherwise, getMapperClass() returns ExecMapper#class.
> Make RLIKE/REGEXP run end-to-end by updating VectorizationContext
