> Spark Partition Pruning Sink Operator can't target multiple Works

>
> Key: HIVE-17178
> URL: https://issues.apache.org/jira/browse/HIVE-17178
> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Reporter: Sahil Takiar
> Assignee: Rui Li
> Priority: Major

> A Spark Partition Pruning Sink Operator cannot be used to target multiple Map
> Work objects. The entire DPP subtree (SEL-GBY-SPARKPRUNINGSINK) is duplicated
> if a single table needs to be used to target multiple Map Works.
> The following query shows the issue:
> {code}
> set hive.spark.dynamic.partition.pruning=true;
> set hive.auto.convert.join=true;
> create table part_table_1 (col int) partitioned by (part_col int);
> create table part_table_2 (col int) partitioned by (part_col int);
> create table regular_table (col int);
> insert into table regular_table values (1);
> alter table part_table_1 add partition (part_col=1);
> insert into table part_table_1 partition (part_col=1) values (1), (2), (3),
> (4);
> alter table part_table_1 add partition (part_col=2);
> insert into table part_table_1 partition (part_col=2) values (1), (2), (3),
> (4);
> alter table part_table_2 add partition (part_col=1);
> insert into table part_table_2 partition (part_col=1) values (1), (2), (3),
> (4);
> alter table part_table_2 add partition (part_col=2);
> insert into table part_table_2 partition (part_col=2) values (1), (2), (3),
> (4);
> explain select * from regular_table, part_table_1, part_table_2 where
> regular_table.col = part_table_1.part_col and regular_table.col =
> part_table_2.part_col;
