Zoltan Chovan created HIVE-15792:
------------------------------------
Summary: Hive should raise SemanticException when LPAD/RPAD pad
character's length is 0
Key: HIVE-15792
URL: https://issues.apache.org/jira/browse/HIVE-15792
Project: Hive
Issue Type: Bug
Reporter: Zoltan Chovan
Priority: Minor
For example SELECT LPAD('A', 2, ''); will cause an infinite loop and the
running query will hang without any error.
It would be great if this could be prevented by checking the pad character's
length and if it's 0 then throw a SemanticException.
