> Delete on ACID enabled table provides wrong results

>                 Key: HIVE-11725
>                 URL: https://issues.apache.org/jira/browse/HIVE-11725
>             Project: Hive
>          Issue Type: Bug
>            Reporter: Rajesh Balamohan
>
> This is based on the master codebase (last commit: 492c8b1d88ffcb68ba4f77a3a49ae8fc768cdd7c)
> Created a table with TBLPROPERTIES("transactional"="true", "NO_AUTO_COMPACTION"="true").
 Populated bunch of records in the table and deleted few of them. Select query after delete
does not seem to consider the deleted records.
