[jira] [Created] (HIVE-17069) Refactor OrcRawRecrodMerger.ReaderPair

Eugene Koifman created HIVE-17069:
-------------------------------------

             Summary: Refactor OrcRawRecrodMerger.ReaderPair
                 Key: HIVE-17069
                 URL: https://issues.apache.org/jira/browse/HIVE-17069
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 3.0.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


this should be done post HIVE-16177 so as not to obscure the functional changes completely

Make ReaderPair an interface
ReaderPairImpl - will do what ReaderPair currently does, i.e. handle "normal" code path
OriginalReaderPair - same as now but w/o incomprehensible override/variable shadowing logic.
Perhaps split it into 2 - 1 for compaction 1 for "normal" read with common base class.

Push discoverKeyBounds() into appropriate implementation
