-----------------------------------

             Summary: NPE in SparkPartitionPruningSinkOperator#closeOp for query with partitioned
join in subquery
                 Key: HIVE-17219
                 URL: https://issues.apache.org/jira/browse/HIVE-17219
             Project: Hive
          Issue Type: Sub-task
    Affects Versions: 3.0.0
            Reporter: Sahil Takiar
            Assignee: Sahil Takiar


The following query: {{select * from partitioned_table1 where partitioned_table1.part_col
in (select partitioned_table2.col from partitioned_table2 join partitioned_table3 on partitioned_table3.col
= partitioned_table2.part_col)}} throws a NPE in {{SparkPartitionPruningSinkOperator#closeOp}}

The full stack trace is:

The full setup is:

{code}
set hive.spark.dynamic.partition.pruning=true;

create table partitioned_table1 (col int) partitioned by (part_col int);
create table partitioned_table2 (col int) partitioned by (part_col int);
create table partitioned_table3 (col int) partitioned by (part_col int);
create table regular_table (col1 int, col2 int);

insert into table regular_table values (0, 0), (1, 1), (2, 2);

alter table partitioned_table1 add partition (part_col = 1);
alter table partitioned_table1 add partition (part_col = 2);
alter table partitioned_table1 add partition (part_col = 3);

insert into table partitioned_table1 partition (part_col = 1) values (1), (2), (3);
insert into table partitioned_table1 partition (part_col = 2) values (1), (2), (3);
insert into table partitioned_table1 partition (part_col = 3) values (1), (2), (3);

alter table partitioned_table2 add partition (part_col = 1);
alter table partitioned_table2 add partition (part_col = 2);
alter table partitioned_table2 add partition (part_col = 3);

insert into table partitioned_table2 partition (part_col = 1) values (1), (2), (3);
insert into table partitioned_table2 partition (part_col = 2) values (1), (2), (3);
insert into table partitioned_table2 partition (part_col = 3) values (1), (2), (3);

alter table partitioned_table3 add partition (part_col = 1);
alter table partitioned_table3 add partition (part_col = 2);
alter table partitioned_table3 add partition (part_col = 3);

insert into table partitioned_table3 partition (part_col = 1) values (1), (2), (3);
insert into table partitioned_table3 partition (part_col = 2) values (1), (2), (3);
insert into table partitioned_table3 partition (part_col = 3) values (1), (2), (3);

select * from partitioned_table1 where partitioned_table1.part_col in (select partitioned_table2.col
from partitioned_table2 join partitioned_table3 on partitioned_table3.col = partitioned_table2.part_col);
{code}

Doesn't seem to happen when map-joins are enabled.
