UPDATE sql statement

Hi,
Having trouble executing "UPDATE" sql statement in cluster:

Whenever try to use "UPDATE" sql statement combined with "EXISTS" condition like:

```
UPDATE table_A T1
SET name="A"
WHERE EXISTS (SELECT 1
FROM table_B T2
WHERE T1.id=T2.parent_id)
```

will get exception like:

```
There are not enough rules to produce a node with desired properties: convention=LOGICAL, sort=(],
DistributionTraitDef=ANY. All the inputs have relevant nodes, however the cost is still infinite.
```
Could anyone maybe give a hint about what's going wrong?
