Eric Wohlstadter created HIVE-20290:
---------------------------------------

             Summary: Lazy initialize ArrowColumnarBatchSerDe so it doesn't allocate buffers during GetSplits
                 Key: HIVE-20290
                 URL: https://issues.apache.org/jira/browse/HIVE-20290
             Project: Hive
          Issue Type: Bug
    Affects Versions: 3.1.0
            Reporter: Eric Wohlstadter
            Assignee: Eric Wohlstadter


When using {{GenericUDTFGetSplits}} to create {{LlapInputSplit}} for submission to {{LlapOutputFormatService}}, the physical plan generation initializes whatever SerDe is being used.

{{ArrowColumnarBatchSerDe}} initializes buffers for Arrow and {{VectorizedRowBatch}} at this point inside HS2 which are never used.
