URL: https://github.com/apache/incubator-doris/issues/6327#issuecomment-892751618
When the child of the Union on the right side of the join is not a constant, it is ScanNode:
```
SELECT a.x
FROM (SELECT '01' x) a
INNER JOIN
(SELECT C_CUSTKEY from CUSTOMER
UNION all
SELECT C_CUSTKEY from CUSTOMER) b;
```
The `Preconditions.checkState` in the FE will report an error
```
java.lang.IllegalStateException: null
