-----------------------------------
+1 pending tests
> ACID major compaction doesn't read base directory correctly if it was written by insert
overwrite
> -------------------------------------------------------------------------------------------------

> Key: HIVE-23442
> URL: https://issues.apache.org/jira/browse/HIVE-23442
> Project: Hive
> Issue Type: Bug
> Affects Versions: 4.0.0
> Reporter: Marta Kuczora
> Assignee: Marta Kuczora
> Priority: Major
> Fix For: 4.0.0
>
> Attachments: HIVE-23442.1.patch, HIVE-23442.2.patch
>
>
> Steps to reproduce:
> {noformat}
> SET hive.acid.direct.insert.enabled=true;
> CREATE EXTERNAL TABLE test_comp_txt(a int, b int, c int) STORED AS TEXTFILE;
> INSERT INTO test_comp_txt values (1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4);
> CREATE TABLE test_comp(a int, b int, c int) STORED AS ORC TBLPROPERTIES('transactional'='true');
> INSERT OVERWRITE TABLE test_comp SELECT * FROM test_comp_txt;
> UPDATE test_comp SET b=55, c=66 WHERE a=2;
> DELETE FROM test_comp WHERE a=4;
> UPDATE test_comp SET b=77 WHERE a=1;
> SELECT * FROM test_comp;
> 3 3 3
> 2 55 66
> 1 77 1
> ALTER TABLE test_comp COMPACT 'MAJOR';
> SELECT * FROM test_comp;
> 2 55 66
> 1 77 1
> {noformat}
> This issue only occurs if the base directory was created with an insert overwrite command
and the hive.acid.direct.insert.enabled parameter was true. This issue doesn't affect the
query based compaction.
