Prasanth Jayachandran reassigned HIVE-17562:
--------------------------------------------
> ACID 1.0 + ETL strategy should treat empty compacted files as uncovered deltas
> ------------------------------------------------------------------------------
>
> Key: HIVE-17562
> URL: https://issues.apache.org/jira/browse/HIVE-17562
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.4.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
>
> In branch-2, with ACID 1.0, following sequence will result in incorrect
> results
> 1) Set split strategy to ETL
> 2) Insert some rows
> 3) Delete all rows
> 4) Alter table compact MAJOR
> 5) Insert some rows
> 6) Select * query will not return any rows that is written at last (step 5)
> The reason for that, compaction essentially voids the first insert in step 2.
> Now when ETL split strategy is chosen, there will not be any stripes in the
> base files. So no split gets generated and any subsequent deltas gets ignored.
