when output meet order by not meet distribution. we use a trick way to
do enforce by set current output to any. but when we do enforce later,
we still use the old output. So when we do choose best plan, we could
not find the older output's plan, since we have replace it by any.
For example:
```
lowest Plan(cost, properties, plan, childrenRequires)
18.0 ANY
id:138#4 cost=0 [0/0/0/] estRows=4 children=[@0 ] (plan=PhysicalWindow[139]@4 ( windowFrameGroup=(Funcs=[row_number() WindowSpec(PARTITION BY b#1, a#0 ROWS BETWEEN UNBOUNDED_PRECEDING AND CURRENT_ROW) AS `r1`#2], PartitionKeys=[b#1, a#0], OrderKeys=[], WindowFrame=WindowFrame(ROWS, UNBOUNDED_PRECEDING, CURRENT_ROW)), requiredProperties=[DistributionSpecHash ( orderedShuffledColumns=[1, 0], shuffleType=REQUIRE, tableId=-1, selectedIndexId=-1, partitionIds=[], equivalenceExprIds=[[1], [0]], exprIdToEquivalenceSet={0=1, 1=0} ) Order: ([b#1 asc, a#0 asc])], stats=null ))
[DistributionSpecHash ( orderedShuffledColumns=[0], shuffleType=NATURAL, tableId=3547296, selectedIndexId=3547297, partitionIds=[3547295], equivalenceExprIds=[[0]], exprIdToEquivalenceSet={0=0} ) Order: ([b#1 asc, a#0 asc])]
32.01171875 DistributionSpecHash ( orderedShuffledColumns=[1], shuffleType=REQUIRE, tableId=-1, selectedIndexId=-1, partitionIds=[], equivalenceExprIds=[[1]], exprIdToEquivalenceSet={1=0} ) Order: ([b#1 asc])
id:161#4 cost=14 [4/4/4/] estRows=4 children=[@4 ] (plan=PhysicalQuickSort[162]@4 ( orderKeys=[b#1 asc], phase=LOCAL_SORT, stats=null ))
[DistributionSpecHash ( orderedShuffledColumns=[0], shuffleType=NATURAL, tableId=3547296, selectedIndexId=3547297, partitionIds=[3547295], equivalenceExprIds=[[0]], exprIdToEquivalenceSet={0=0} ) Order: ([b#1 asc, a#0 asc])]
32.01171875 DistributionSpecHash ( orderedShuffledColumns=[1], shuffleType=EXECUTION_BUCKETED, tableId=-1, selectedIndexId=-1, partitionIds=[], equivalenceExprIds=[[1]], exprIdToEquivalenceSet={1=0} ) Order: ([b#1 asc])
id:161#4 cost=14 [4/4/4/] estRows=4 children=[@4 ] (plan=PhysicalQuickSort[162]@4 ( orderKeys=[b#1 asc], phase=LOCAL_SORT, stats=null ))
[DistributionSpecHash ( orderedShuffledColumns=[1], shuffleType=EXECUTION_BUCKETED, tableId=-1, selectedIndexId=-1, partitionIds=[], equivalenceExprIds=[[1]], exprIdToEquivalenceSet={1=0} ) Order: ([])]
18.01171875 DistributionSpecHash ( orderedShuffledColumns=[1], shuffleType=EXECUTION_BUCKETED, tableId=-1, selectedIndexId=-1, partitionIds=[], equivalenceExprIds=[[1]], exprIdToEquivalenceSet={1=0} ) Order: ([])
id:157#4 cost=0 [0/0/0/] estRows=4 children=[@4 ] (plan=PhysicalDistribute[158]@4 ( distributionSpec=DistributionSpecHash ( orderedShuffledColumns=[1], shuffleType=EXECUTION_BUCKETED, tableId=-1, selectedIndexId=-1, partitionIds=[], equivalenceExprIds=[[1]], exprIdToEquivalenceSet={1=0} ), stats=null ))
[DistributionSpecHash ( orderedShuffledColumns=[0], shuffleType=NATURAL, tableId=3547296, selectedIndexId=3547297, partitionIds=[3547295], equivalenceExprIds=[[0]], exprIdToEquivalenceSet={0=0} ) Order: ([b#1 asc, a#0 asc])]
```
the last one require a natural shuffle type property from this group.
but this property already been removed when we do
enforceDistributionButMeetSort. So, such exception will be thrown
