Eric Hanson created HIVE-5490:
---------------------------------
Summary: SUBSTR(col, 1, 0) returns wrong result in vectorized mode
Key: HIVE-5490
URL: https://issues.apache.org/jira/browse/HIVE-5490
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.13.0
Reporter: Eric Hanson
Priority: Minor
The query
select substr(cstring1, 1, 0) from alltypesorc;
returns all empty strings when
set hive.vectorized.execution.enabled = false;
which is the correct result, and returns non-empty strings when
set hive.vectorized.execution.enabled = true;
which is not correct.
