Teddy Choi created HIVE-21256:
---------------------------------
Summary: Vectorized LENGTH UDF doesn't respect the max length of
VARCHAR or CHAR in Hive 2
Key: HIVE-21256
URL: https://issues.apache.org/jira/browse/HIVE-21256
Project: Hive
Issue Type: Bug
Affects Versions: 2.3.4
Reporter: Teddy Choi
Assignee: Teddy Choi
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.
