> After HIVE-19951 is fixed, there still are some cases that vectorized length UDF doesn't respect the max length of VARCHAR or CHAR. StringLength has an internal bug. Moreover, it's hard to get input data type details in Hive 2, unlike Hive 3. So separate both implementation to keep code clean in Hive 3 while the changes minimal in Hive 2.
