> 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.
