Kazuaki Ishizaki 3c3eebc873 [SPARK-20101][SQL] Use OffHeapColumnVector when "spark.sql.columnVector.offheap.enable" is set to "true" ... This PR enables to use ``OffHeapColumnVector`` when ``spark.sql.columnVector.offheap.enable`` is set to ``true``. While ``ColumnVector`` has two implementations ``OnHeapColumnVector`` and ``OffHeapColumnVector``, only ``OnHeapColumnVector`` is always used. This PR implements the followings - Pass ``OffHeapColumnVector`` to ``ColumnarBatch.allocate()`` when ``spark.sql.columnVector.offheap.enable`` is set to ``true`` - Free all of off-heap memory regions by ``OffHeapColumnVector.close()`` - Ensure to call ``OffHeapColumnVector.close()`` Use existing tests Author: Kazuaki Ishizaki <ishizaki@jp.ibm.com> Closes #17436 from kiszk/SPARK-20101.		2017-11-20 12:40:26 +01:00
