Good catch. We need to have a way to automatically convert any columnar format to Velox format. Do we need to hack spark code to do the conversion? |
Yes, we already have the transition system to insert the convertions automaically in query planning phase. This bug specifically applies to columnar table cache feature since the conversions are expected to be done at execution time.
For fixing this issue, I am not sure yet. Will keep looking for solutions. |

#8497
Add a bad case which is ignored at the moment to reproduce the bug described in #8497.
I am still looking for a proper solution of the bug. Could merge the test code in advance so one could try with it if interested.
