Ashutosh Chauhan commented on HIVE-18999:
-----------------------------------------
Although this fixes the issue, its not an ideal solution. e.g., this fix
doesn't address vectorization case. So, this will still be an issue on
vectorized path.
Compiler should generate type safe plan and runtime shouldn't be responsible
for 'fixing' up type mismatch. So, correct fix is to insert these casts in
TypeCheckProcFactory when we generate ExprNodeDesc from AST.
