----------------------------------------------
> Minor compaction writes delete records in unbucketed tables multiple times

> -----------------------------------------------------------------------------------------------------------------

> Key: HIVE-21710

> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
> Priority: Major
>
> For a given delete delta directory in an unbucketed table,
> {{OrcRawRecordMerger}} returns the records in all files {{bucketN}}. However,
> minor compaction is triggered per bucket, leading to writing all delete
> records in each different bucket destination file in the new delete delta
> directory.
