@deniskuzZ , need some advice here. In the q file present in this PR, if i
enable vectorization then it is failing with the following error. I observed
the original stacktrace in hive-sever2.err in prod in Hive 4.0.1 (Not sure if
user has disabled vectorization at beeline session but this is my best guess).
I think work done similar to HIVE-29649, needs to be done if we want to enable
String to Date vectorized conversion?
