Peter Vary created HIVE-22805:
---------------------------------
Summary: Vectorization with conditional array or map is not
implemented and throws an error
Key: HIVE-22805
URL: https://issues.apache.org/jira/browse/HIVE-22805
Project: Hive
Issue Type: Bug
Components: Vectorization
Reporter: Peter Vary
Assignee: Peter Vary
The following queries throw an "Not supported" Exception:
{code}
DROP TABLE IF EXISTS cond_vector;
CREATE TABLE cond_vector(a STRING) STORED AS ORC;
INSERT OVERWRITE TABLE cond_vector VALUES("a/b");
set hive.fetch.task.conversion=minimal;
set hive.execution.mode=container;
SELECT IF(1=1, MAP("a","b"), NULL) FROM cond_vector;
EXPLAIN VECTORIZATION DETAIL SELECT IF(1=1, MAP("Mathematics","78"), NULL) FROM
cond_vector;
SELECT IF(1=1, ARRAY("c", "d"), NULL) FROM cond_vector;
EXPLAIN VECTORIZATION DETAIL SELECT IF(1=1, ARRAY("a", "b"), NULL) FROM
cond_vector;
{code}
One example of the Exception (maybe not exactly this on 4.0.0 branch, but close
enough to check):
{code}
