-------------------------------------------
Summary: ACID: Pick the compactor transaction over insert dir
Key: HIVE-25777
URL: https://issues.apache.org/jira/browse/HIVE-25777
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 3.1.2, 4.0.0
Reporter: Gopal Vijayaraghavan
If there are two competing versions of a particular write-id, one from the
compactor and another from the original insert, always pick the compactor one
once it is committed.
If the directory structure looks like
{code}
base_000011/
base_000011_v192/
{code}
Then always pick the v192 transaction if txnid=192 is committed.
This is required to ensure that the raw base_ dir can be deleted safely on
non-atomic directory deletions (like s3), without a race condition between
getSplits and the actual file-reader.
