[jira] [Created] (HIVE-3226) ColumnPruner is not working on
LateralView
Navis created HIVE-3226:
---------------------------
Summary: ColumnPruner is not working on LateralView
Key: HIVE-3226
URL: https://issues.apache.org/jira/browse/HIVE-3226
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.10.0
Reporter: Navis
Assignee: Navis
Column pruning is not applied to LVJ and SEL operator, which makes exceptions at various stages. For example,
{noformat}
drop table array_valued_src;
create table array_valued_src (key string, value array<string>);
insert overwrite table array_valued_src select key, array(value) from src;
select sum(val) from (select a.key as key, b.value as array_val from src a join array_valued_src b on a.key=b.key) i lateral view explode (array_val) c as val;
... 9 more
Caused by: java.lang.RuntimeException: Reduce operator initialization failed
