Description

set hive.stats.column.autogather=false;

set hive.exec.dynamic.partition.mode=nonstrict;
set hive.exec.max.dynamic.partitions.pernode=200;
set hive.exec.max.dynamic.partitions=200;
set hive.support.concurrency=true;
set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;

create table i0 (p int,v int);
insert into i0 values
        (0,0),
        (2,2),
        (3,3);

create table p0 (v int) partitioned by (p int) stored as orc 
  tblproperties ("transactional"="true", "transactional_properties"="insert_only");

explain insert overwrite table p0 partition (p) select * from i0 where v < 3;
insert overwrite table p0 partition (p) select * from i0 where v < 3;
select count(*) from p0 where v!=1;

The table p0 should contain 2 rows at this point; but the result is 0.

• seems to be specific to insert_only tables
• the existing data appears if an insert into is executed.
