-------------------------------------
Summary: Acid Load Data/Insert with Overwrite in multi statement
transactions
Key: HIVE-18154
URL: https://issues.apache.org/jira/browse/HIVE-18154
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 3.0.0
Reporter: Eugene Koifman
Assignee: Eugene Koifman
Consider:
{noformat}
START TRANSACTION
insert into T values(1,2),(3,4)
load data local inpath '" + getWarehouseDir() + "/1/data' overwrite into table T
update T set a = 0 where a = 6
COMMIT
{noformat}
So what we should have on disk is
{noformat}
├── base_0000028
│ ├── 000000_0
│ └── _metadata_acid
├── delete_delta_0000028_0000028_0002
│ └── bucket_00000
├── delta_0000028_0000028_0000
│ └── bucket_00000
└── delta_0000028_0000028_0002
└── bucket_00000
{noformat}
where base_28 is from overwrite, delta_0000028_0000028_0000 from 1st insert nad
delta_0000028_0000028_0002/delete_delta_0000028_0000028_0002 is from update.
AcidUtils.getAcidState() only returns base_28 thinking that all other deltas
are included in it - not what we want here.
The simple way to get correct behavior is to disallow commands with Overwrite
clause in multi-statement txns.
