morrySnow opened a new pull request, #23973:

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)

```
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
```
