**What would you like to be improved?** `TableEntity.equals` compares `columns` with `CollectionUtils.isEqualCollection` (order-independent, bag semantics), but `hashCode` hashes the `List` directly, which is order-sensitive. Two tables that are equal under `equals` but differ only in column ordering get different hash codes, which violates the `Object.hashCode` contract and loses them in any `HashSet` or `HashMap`. The old `hashCode` argument list also included `distribution` twice. **How should we improve?** Combine an order-independent sum of element hashes for `columns` into `hashCode`, matching exactly the fields `equals` compares, and drop the duplicated `distribution` argument. `partitioning`, `sortOrders`, and `indexes` are compared with `Arrays.equals` (order-sensitive) on both sides, so their `Arrays.hashCode` stays as is. -- This is an automated message from the Apache Git Service.
