    Description

      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.
