> "get_splits" udf ignores limit constraint while creating splits
> ---------------------------------------------------------------
>
> Key: HIVE-23230
> URL: https://issues.apache.org/jira/browse/HIVE-23230
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 3.1.0
> Reporter: Adesh Kumar Rao
> Assignee: Adesh Kumar Rao
> Priority: Major
> Attachments: HIVE-23230.1.patch, HIVE-23230.2.patch,
> HIVE-23230.3.patch, HIVE-23230.4.patch, HIVE-23230.patch
>
>
> Issue: Running the query {noformat}select * from <table> limit n{noformat}
> from spark via hive warehouse connector may return more rows than "n".
> This happens because "get_splits" udf creates splits ignoring the limit
> constraint. These splits when submitted to multiple llap daemons will return
> "n" rows each.
> How to reproduce: Needs spark-shell, hive-warehouse-connector and hive on
> llap with more that 1 llap daemons running.
> run below commands via beeline to create and populate the table
>
> {noformat}
> create table test (id int);
> insert into table test values (1);
> insert into table test values (2);
> insert into table test values (3);
> insert into table test values (4);
> insert into table test values (5);
> insert into table test values (6);
> insert into table test values (7);
> delete from test where id = 7;{noformat}
> now running below query via spark-shell
> {noformat}
> import com.hortonworks.hwc.HiveWarehouseSession
> val hive = HiveWarehouseSession.session(spark).build()
> hive.executeQuery("select * from test limit 1").show()
> {noformat}
> will return more than 1 rows.
