The root cause is that we have the wrong `CopyExec` mode in the following
native plan, leading to memory corruption due to reuse of mutable buffers.
```
SortExec: expr=[col_0@0 ASC, col_2@2 ASC], preserve_partitioning=[false]
CopyExec [UnpackOrClone]
FilterExec: col_0@0 IS NOT NULL
ScanExec: source=[CometBatchScan testhadoop.default.table (unknown)],
schema=[col_0: Int64, col_1: Int32, col_2: Timestamp(Microsecond, Some("UTC"))]
```
