[jira] [Created] (HIVE-12403) Too many delta files during Compaction - OOM Part Deux

Eugene Koifman created HIVE-12403:
-------------------------------------

             Summary: Too many delta files during Compaction - OOM Part Deux
                 Key: HIVE-12403
                 URL: https://issues.apache.org/jira/browse/HIVE-12403
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 1.3.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


HIVE-11540 solution is somewhat incomplete.
Suppose hive.compactor.max.num.delta=10 and there are 1000 delta files to compact.

CompactorMR will currently run 100 jobs on 10 files each to create 100 wider delta files but then it will run 1 job which will include 100 of the wider deltas.

it's a simple fix to make sure the max.num.delta is always respected
