Review comment:
```
SPARK-35378: Commands should be executed eagerly so that `sql("INSERT ...")`
can trigger the
table insertion immediately without a `.collect()`. We also need to eagerly
execute non-root commands,
because many commands return `GenericInternalRow` and can't be put in a
query plan directly, otherwise
the query engine may cast `GenericInternalRow` to `UnsafeRow` and fail
```
