Description:
In vectorized expressions, from time to time, I see a similar/same logic to be
repeated, which always consists of some stuff like:
1. some inner loops (even the comments are the same)
{code}
grep -iRH "Set isNull before call in case it changes it mind" | grep
"ql/src/java/org/apache/hadoop/hive/ql/exec/vector/expressions/"
{code}
2. call to an actual "business logic" function ==> 1 line which could be
abstracted... and it has been abstracted in hive codebase in n different cases.
However, an abstract BaseVectorExpression would not force anybody to extend it
instead of VectorExpression and not copy the code again, but it could be a good
start and an example.
