[jira] [Created] (HIVE-21710) Minor compaction writes delete records in unbucketed tables multiple times when we have multiple files

Jesus Camacho Rodriguez created HIVE-21710:
----------------------------------------------

             Summary: Minor compaction writes delete records in unbucketed tables multiple times when we have multiple files <bucket_N>
                 Key: HIVE-21710
                 URL: https://issues.apache.org/jira/browse/HIVE-21710
             Project: Hive
          Issue Type: Bug
          Components: Transactions
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


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.
