> ---------------------------------------------------------------
>
> Key: HIVE-21660
> URL: https://issues.apache.org/jira/browse/HIVE-21660
> Project: Hive
> Issue Type: Bug
> Components: Physical Optimizer
> Affects Versions: 3.1.1
> Reporter: Ganesha Shreedhara

> There is a data loss when the data is inserted to a partitioned table using
> union all and lateral view with explode.
>
> *Steps to reproduce:*
>
> {code:java}
> create table t1 (id int, dt string);
> insert into t1 values (2, '2019-04-01');
> create table t2( id int, dates array<string>);
> insert into t2 select 1 as id, array('2019-01-01','2019-01-02','2019-01-03')
> as dates;
> create table dst (id int) partitioned by (dt string);
> set hive.exec.dynamic.partition.mode=nonstrict;
> set hive.exec.dynamic.partition=true;
> insert overwrite table dst partition (dt)
> select t.id, t.dt from (
> select id, dt from t1
> union all
> select id, dts as dt from t2 tt2 lateral view explode(tt2.dates) dd as dts )
> t;
> select * from dst;
> {code}
>
>
> *Actual Result:*
> {code:java}
> +--------------+--------------+
> | 2 | 2019-04-01 |
> +--------------+--------------+{code}
>
> *Expected Result* (Run only the select part from the above insert query)*:*
> {code:java}
> +-------+------------+
> | 2 | 2019-04-01 |
> | 1 | 2019-01-01 |
> | 1 | 2019-01-02 |
> | 1 | 2019-01-03 |
> +-------+------------+{code}
>
> Data retrieved using union all and lateral view with explode from second
> table is missing.
