------------------------------------------
LGTM +1 (also for .14. fixes major issue and the change is small/safe).
> Sorted dynamic partition does not work correctly with constant folding

> Sorted dynamic partition optimization looks for partition columns from the
> operator above FileSinkOperator. As per hive convention it expects partition
> columns at the last. But with HIVE-8585 equality filters on partition columns
> gets folded to constant. The column pruner then prunes the constant
> expression as they don't reference any columns. This in some cases will yield
> unexpected results (throw ArrayIndexOutOfBounds exception) with sorted
> dynamic partition insert optimization. In such cases we don't really need
> sorted dynamic partition optimization.
