Ferdinand Xu commented on HIVE-18553:
-------------------------------------
At my current understanding, rename or type conversion may require index
access. It may not work for the current workaround for vectorization path. We
can spend some time to investigate it for fully support. The current patch can
be considered as a quick workaround. Any thoughts on this?
